Recording of Joaquin Orellana's "Rupestre en el futuro" for tape. Extra-musically, the piece is a "testimony of place" in a surrealist picture of a social situation, namely, the development of humans. The beginning of the piece uses phonemes in indigenous languages (Quiché, Tzutujil) and special instruments made by the composer to simulate the sounds of "a supposed primitive man."

Recording of Eugeniusz Rudnik's Moulin Diabolique" ("Devilish Mill"). The work consists of six sequence that have their own dramatic, musical, and architectural meaning independent of the piece as a whole. The piece is based on military orders in different languages, as well as the sounds emitted by human groups (soldiers), which constitute the answer itself or accompany the answer that is required. The composer processes the sounds of the orders to deepen the grotesque and lugubrious character that these orders contain.
