With "Ontologie" Entre Vifs offer a selection of extracts from their best recent sessions. Each of these excerpts has been cautiously positioned by the authors, so that they appear like bruitist pieces, composed with care, even though all of these pieces are played live. A symphony of noises, extremely varied in intensity and frequency, where one can distinguish the sound detached from its original source. Entre Vifs' noise generators are delicate and relatively small in size, but the sounds they produce through mechanical means are captured by electric guitar pickups and piezoelectric cells, then sent to a battery of amplifiers and homemade effect processors. The sound is huge, with a stereophonic depth effect where sonic masses seem to thicken and change continuously.
