The first major publication on one of the most important Lettrist artists: the catalogue raisonné of Roberto Altmann's engraved work, with 200 works described, an interview with Maggy Mauritz, a biography and a list of exhibitions.Frédéric Acquaviva, born in 1967, has been since 1990 a sound artist and experimental music composer, creating chronopolyphonic installations and CDs and playing in art galleries, in museums or in underground venues.Staying away from traditional networks of musicians and composers, he meets and works with historical figures in art, poetry or video, sometimes a long time before their being discovered by the media.

He has collaborated this way with Isidore Isou, Maurice Lemaître, Marcel Hanoun, Pierre Guyotat, Jean-Luc Parant, mezzo-soprano Loré Lixenberg, film maker FJ Ossang and choreographer Maria Faustino, among others.His astonishing music, in which he chooses an experimental presentation using, is constantly exploring, always in new ways, the relationship between voice and language, sound and its meaning, even the idea of physical body sounds integrated into the musical composition, kept away from the concert hall's diffusions (acousmatic or sound installations). As the critic Eric Vautrin remarked in Mouvement magazine, his work is not a “sound work but a work about sound”.

Acquaviva has become not only one of the essential protagonists of the rediscovery of historical avant-garde, more precisely of Lettrism (Isidore Isou, Gabriel Pomerand, Maurice Lemaître, Gil J Wolman, Jean-Louis Brau, Jacques Spacagna, François Dufrêne, Roland Sabatier, Alain Satié, Broutin), but of Sound Poetry (Henri Chopin, Bernard Heidsieck), and has worked with some unique and outstanding historical figures (Pierre Albert-Birot, Otto Muehl). He has done this through his knowledge of and interest in different disciplines: editing books, curating art exhibitions, being an events creator, lecturing, establishing catalogue raisonnés and bibliographic databases, creating radiophonic works, being an art critic, a filmmaker, and a publisher, with Editions Derrière la Salle de Bains or for his own editions: AcquAvivA, and the magazine CRU.
