Major artists of XXI century stay hidden, and you need talent to discover them
des trajectoires audibles dans l'espace ?

Since 1997, centrebombe is online, on the Internet, an open door offering the music works of Myster Mathius Shadow-Sky and some talented friends. Since that time; 18 years, there is no real human feedback as expected? like an invitation for an original music creation somewhere on Earth with human friendly contact; according of what was done since 36 years of Mathius Shadow-Sky original music creation, thought, and theory. The function of the website made for users, is to feed for free music lovers (there is approximatively 100 albums downloaded per month at But is it enough?
He Ho? Somebody there?

"Internet network is not free (but it should be): I have to pay personally for this permanent presence: pay my name (the domain name), pay to park my music works for you to download it for free out of aggressive commercials. To pay for you, to get knowledge for free for you, isn't it a paradox?"

"I have touched the limit of enjoyment (by feedback absence): and I am asking you, anonymous users, what I have to do? Tell me: or just an email telling: Thank You"

since 1996:
Mathius Shadow-Sky is building another age for symphonic music
with the Trans-Cultural Syn-phônê Orchestras from the world

The last attempt to gather 100 musicians from all genre in an orchestra for an original symphonic music creation, was in Berlin in 2007. The economic censorship was too strong for Mathius Shadow-Sky to fight, and makes him forced to cancel the project. Many TCSO are waiting around the world since 1997.

since 80s:
Mathius Shadow-Sky is building another age for Trans-Class Orchestras: 1984-90 Ono Lulu Filharmonia, 2005-06 the Shadow-Sky-Ensembles, 2007-08 L'Extrême Sonique Sans Concession Réuni

Since 1981:
Mathius Shadow-Sky is building another age for opera:
Momus (1981), Test-Aimant (2004), La Farsa Humana (2005), No Things (2001),
De l'Extase la Musique Extreme (2007), Les Rescapés de l'Hégémonie Culturelle (2008), Bellone the Slope of War (201x?), ta Maison à TOLERANCIA (2018)

The time of opera are not done like most of composers like to say by lack of access to the means. Opera today is still performed and thought like in XIX century: in the same opera house with the same education in classical school of music. For an original alive composer, it is a nightmare. The way to make a different opera form, is to leave the opera house, and work without the unlimited means of the genre made for the glory of rich people exploiting poorness.

1980-2007: the history of the Lamplayer 2600 BC to 2007 AD

To create a musical instrument from an usual object with a result of sophisticated music from 5000 years sounding calandar was a way to demonstrate that original music can come from everything: not only from avant-garde and technology.

Since 1995 Mathius Shadow-Sky, thanks to Gyorgy Kurtag jr, appeal to re:compose music from XX century contemporary composers calls :

XX Century Contemporary Composers Re:composed by the next generation composers

A tribute to these XX century composers who was free to compose and release their works among an enthusiastic audience: the major lack of our next generation that fights mostly against censorship.



The consequences of: royalties thief, the thief of artists copyright, the obligation for artists to pay their own royalties to publish their works, the propaganda prosecution as criminals against artists giving their own works for free on the Internet, and so on; make that Mathius Shadow-Sky creates in 2003 a sign of recognition about copyright abuse with a book of many examples that prove copyright paradox: music and property does not work together. SACEM is in France the most important private company collecting royalties for music where Mathius Shadow-Sky is a member since 1980. In 2004 he asked for his resignation, but the SACEM ignore its demand and continue to collect his royalties without paying him.

Like most of composers and musicians accumulating a huge amount of knowledge by their specific exploration and experiences. Mathius Shadow-Sky starts to assemble his writing since 1979 in 2007 about music technique for music composition, but in 2008, by a circumstance of cultural political abuse, he started trying to understand links between original music creation and politic power, the strong fight between artists and politicians: the origin of censorship. The book is written in French, not yet translated in English.

« Le livre : Dans le Ciel, le Bruit de l'Ombre, est un livre évoluant en ligne. L'idée est que ce livre réjouisse de ce que la vie nous offre. Tout en accrochant les frustrés et les croyances qui peinent les autres. Il y a aussi de la cuisine de compositeur que les non-musiciens peuvent éviter. La vibration du monde est comprise à partir de la musique. Sachant que la musique est le reflet vibratoire des idées et des attitudes humaines. Je manque de retour quant à mes écrits. Ma musique je sais, personne ne la comprend ! quoique mes écrits aussi, ah ah. Moi-même, le mystère de l'ombre dans le ciel ; que veux-je ? Comme tous, vivre & jouir de vivre. »

Now on [since December 2013] THE EPHEMERODE CARDS OF CHRONES [piano recital]
(the Ephemerode cards some chrones) the Ephemerode is an ephemeral prowler which resolve time knots by playing an unheard music flying in a real 3D space with uncountable & unidentifiable pianomorphes (keyboards in a perpetual morphing).

Myster Shadow-Sky plays uncountable & unidentifiable pianomorphes, a recital in a moving octophonic 3D space with audio trajectories percing the audience bodies by moving inside. In a cubic octophonic P.A. with no stage: a convivial space design to perform among the audience (sponsored by Pianoteq, WAF, Scala, Spatial Processor).

The majority of composer-musicians without orchestra turned to the piano recital. The keyboard is the representative instrument of the Western polyphonic music for a solo musician. (I have in mind: Colow Nancarrow who as a nonpiano performer used a player piano roll, I have in mind: La Monte Young and his "just intonation" tuned piano, I think also about Diamanda Galas who ended her voice career with the piano recital, I think also about Keith Jarret or the without audience recital performer Glenn Gould (as J.S. Bach piano-refuge), I think also about List, Chopin, Mozart and all the many others.) The 10 fingers keyboard music supports the Western harmony development (and the human Western isolation). It is a tradition to use the piano keyboard (with the need of a serious evolution according to the shape of our 10 fingers 2 hands, is now still the no-other-choice to notice the thinking music) to listen other harmonies as now nonoctave. Our digital keyboard softwares system allow to listen to nonoctave harmony with unheard sounds, both in metamorphosis with multiple keyboards at the same time..

+ Now off [since September 1995] Aloof Proof + Myster Shadow-Sky

"The Secret becomes Revelation: a noncultural acoustic music duet with no P.A. It involves Mathius Shadow-Sky playing Asian acoustic musical instrument (Dan Tranh & Jinghu) plus its nonoctave electric guitar and the inharmonic analogue synthesizer ElectroHarmonix/Mono/Poly, together with the young musician Bertrand Fraysse playing percussion and gong drums. The focus of the music is to reach the sublime: simple and effective. The concert is convivial, they are playing among the audience in a warm and friendly atmosphere. A different way to communicate with music outside usual classical stage."

Aloof Proof and Myster Shadow-Sky are performing since 1997. They recorded 3 albums: 1. ALOOF SKY IS THE PROOF OF SHADOW (1997), 2. ALIVE IN UNBELIEVABLE UNIVERSES (2006), 3. A BRIEF RETURN TO EARTH (2013)

- Who is Mathius Shadow-Sky?
- Mathius Shadow-Sky is the first unknown major composer of the Western history of music, the major space composer after Stockhausen and Xenakis.
- Why Mathius Shadow-Sky is an important composer in Western Music?
- Beside being productive, creative, and original with honesty, Mathius Shadow-Sky extended the Western music theory called: the Scalar Field Music Theory (as important as Johann Sebastian Bach did 300 years ago) based on nonoctave scales. He revolutionizes the concept of music writing by introducing non-linear score first by injecting the Game-form in music with unfixed music duration. He revolutionizes the concept of musical writing by figuring unwritable multidimensional mapping score. He is the one composer that creates tridimensional XYZ full space trajectories music interacting with other attributes (started in 1982 with Ourdission). His deep spirit of freedom and open minded drive him to write (...).
- Mathius Shadow-Sky is it a music pioneer?
- Who cares?

Heureux anniversaire centrebombe ! en 2017 centrebombe a 20 ans dans le réseau Internet

Ne sommes-nous pas toutes et tous fatigués de tous les obstacles que les êtres humains posent partout entre eux ? Et pour ce qui concerne le savoir, l'empêcher ou le mettre à condition, c'est entretenir volontairement l'ignorance, ressemble à un crime de société. À tout passage, quelqu'un pose un obstacle conditionnel, en général un péage pour traverser ce qui avant était libre. Un chantage et un racket. Cette personne devient un maillon de la chaîne de l'administration gouvernementale reliée au gouvernement relié aux intérêts économiques mondialisés à maintenir les positions de domination et les perpétuer. Ces êtres humains qui se rendent nuisibles à boucher les flux (créer des caillots, des cancers) sont kyrielles à vivre dans le confort du parasitage : leur rêve humain d'agir au minimum pour être nourri (et loger) au maximum (de confort). Tout notre fonctionnement social est fondé sur ce désir et cette impôsition du péage = la masse humaine fleurit quelques élus.

Internet a été créé et remis au public pour l'échange instantané de savoir (sous forme de données numériques) et l'accès gratuit par une prise de téléphone qui aujourd'hui s'étend aux micro-ondes radio du WiFi dont les accès sont fermés par le péage à quelques compagnies privées escrocs à se guerroyer l'appropriation illégale en vertu des principes de sa création. Cette fermeture des accès libres a débuté intensivement au début du XXIe siècle. Jusqu'à la violence (mise en danger et en péril physique des gens) Hadopi (en France) pour le compte de l'industrie du cinéma américain d'Hollywood (le bois saint) avec l'argent public des impôts. Sans compter la réduction du réseau WiFi individuel de 300 Mbps (méga bit : 300 millions de bit par seconde) à 54 jusqu'à 6. À ralentir la durée de recherche de savoir. Toutes les portes qui se ferment depuis l'an 2000 qui se déverrouille partiellement par le péage et le chantage (« register » pour espionnage des désirs privés, influences publicitaires personnalisées, remise des clés de sa boite aux lettres email, intrusion domestique par micro et caméra intégrés, etc.). Les nuisances majeures des sociétés humaines proviennent principalement des gouvernants (autoproclamés constitués d'une armée assassine) et surtout: des gouvernés volontaires. Des organisations telles : Le Projet Gutemberg, ou Ubuweb et tous.tes les Autres (hackers, partageurs, peer-to-peereuses, etc.) sont continuellement attaqué par l'économie du chantage et du racket, mais Centrebombe avec elles continue de donner (sans péage ni registration) depuis + de 20 ans.

ANNIVERSARY: centrebombe in the Internet, date of connection: November 27, 1997. 2017: is 20 years old!



















2016 ugly news: CBS has stolen, without any agreement of the alive composer Mathius Shadow-Sky: his music, his music titles and his name.
In 2017, this aggression is still not repaired and excused by the thieve billionaire Sumner Redstone.




















































l'antre du webart Started in 1997 until 2001 with images and sound interactions, some netart pages with today navigators do not work any more: unfortunately. Due to pursuit of profit and fame of computer tools companies: the action of selfishness destroys means for art.















































Why safely? Why people are fearing artists? because the affluents fear 2 actions from the slaves-loosers: being free, and knowing the thruth. Artists (true, not false) are knowledge makers, truth makers, in contrary of scientists who pretend revealing the thruth which is the picturing of their imagination : the illusion of what it is seen, then believed.

Pourquoi en toute sécurité ? Pourquoi les gens craignent-ils les artistes ? Parce que les influents craignent 2 choses des esclaves (les perdants sociaux) : être libre et connaître la vérité. Les artistes (les vrais, pas les faux) sont des créateurs de savoir, de vérité, contrairement aux scientifiques qui prétendent révéler la vérité qui est l'image de leur imagination : l'illusion de ce qui est vu, puis cru.

Inoffensif = qui n'attaque pas (pas d'offensive, qui n'offense pas), mais alors, pourquoi les propriétaires redoutent-ils tant les artistes à les considérer offensif donc agressif, générateur de souffrance par la violence ? Si un artiste réalisait ça, il serait militaire, pas artiste ! Qu'est-ce que le nanti redoute chez l'artiste ? La liberté et la vérité : 2 actions qui anéantissent le capital volé aux autres.

Inoffensive = that does not attack (no offensive, no offence), but then, why do owners fear so much artists to consider them offensive = aggressive, generator of suffering by violence? If an artist realized that, he would be a soldier in a army, not an artist! What does the owners fear from the artist? Freedom and truth: 2 actions that annihilate the stolen capital to others.
