Rhys Chatham's retrospective box set 'An Angel Moves Too Fast To See' (Table Of Elements) has long been a favourite of mine,so to find new(ish) work by him is a boon. He uses the guitar,trumpet and voice combined into a very unique fingerprint which I find delightful and enervating.He is a key figure in the late-minimalist enclave but for me his music also possesses the power of truth. I read he used to be Glenn Gould's piano tuner at one time...I bet there are some interesting stories there!
Part tribal drone,part Tuvan throat singing,part trumpet deconstruction...all a healing mantra.
Adding guitar and drums to last track is just icing on the cake.
There are Jon Hassell overtones here but they are surely complementary and not derivative.
