João Pais Filipe delivers three acoustic solo percussion works for Ondes HXCX. The tracks were originally recorded for an exhibition called "Membrana" which took place in a church in Northern Portugal, using only drums. Different odd time signatures were extensively explored on each of the tracks. 18/16, 19/16, 23/16 and for the first time, a technique called "omission" was also introduced. It consists of omitting notes of the Rhythm without changing it, creating a sense of illusion and changing the perspective of the Rhythm. Burnt Friedman, an accomplice of João's studies on odd rhythms focused on blending counter-rhythmic electronic elements into the 23/16 track. Ink stamped artwork.
