The fourth album release in the Secret Rhythms series by Burnt Friedman & Jaki Liebezeit results from a ten-year collaborative project encompassing live performances and studio sessions. What began as a rehearsal for a concert delivered at Cologne Triennale 2000 turned into a long-term exploration of the laws governing rhythm. Therefore, this fourth CD is based, like it's predecessors, on a variety of rhythms seldom heard elsewhere.
