A series of eight "voices" for piano, extended minimal works slowly unfolding in the performance of composer Carlo Inderhees' "8 stimmen" composition for solo piano, expressed by Guy Vandromme as the piece answers the questions "what is music made of?" with the word "voices: a sequence of sounds and silences, with its own consistency".

John Cage wrote his "Number Pieces" in the last years of his life, using his time bracket technique of short fragments allowing the performer flexibility in interpretation; each piece is titled for the number of performers and its ordinal position in the series, and most pieces are dedicated to a musician; here pianist Guy Vandromme performs three of the "One", or solo, series.

Burkhard Schlothauer presents two works by John Cage written for septet, using indeterminacy in a score where each instrumental part is given twenty time brackets, allowing overlapping sounds which will be shaped depending on choices from each performer.
