In his most recent Hyperion, Mâche has organised these possibilities in terms of timbre into categories so clearly distinguished that one might find in them the experience of concrete sounds which, after all, fascinate him above all as a composer.

François-Bernard Mâche creates a splendid firework display, exclusively electro-acoustic, and sprung from Saturn.

...François-Bernard Mâche's electroacoustic tape to send a message into Saturnian space with Voyager I.

François-Bernard Mâche's sequence (on the sending into space of the Voyager satellite loaded with messages for extraterrestrials) with sound material that has undergone computer processing is one of the moments that hold the headlines.

François-Bernard Mâche talks about sending a rocket to Saturn, loaded with a message from Jimmy Carter to the extraterrestrials... Mâche's unheard-of electronic sounds...

Mâche's recent Hypérion, which came next on the program, also utilizes natural sounds, but only to be analyzed and regenerated by a computer. The idea, of course, is that once one reduces animal sounds or drum beats to a series of digits in a computer, one can manipulate the information in more ways and with less problems. Of course, it also happens that the sounds become considerably abstracted. In general I found Hypérion less rich in implication and less satisfying in sound than Mâche's more 'phonographic' work.
