Unknown Rivers is bassist Luke Stewart's debut for Pi Recordings. An omnipresent and galvanizing force on the music scene, Stewart is a leader or co-leader of such bands as Irreversible Entanglements, Exposure Quintet, Blacks' Myths, Heart of the Ghost, and Remembrance Quintet. He is also among the most in-demand collaborators, having performed with the likes of David Murray, Nicole Mitchell, Moor Mother, Jaimie Branch, Nate Wooley, Ken Vandermark and countless others. Stewart is also a curator and presenter of multiple concert series in New York and Washington, D.C., a writer, activist, producer and D.J. Featuring his long-running Silt Trio, with Brian Settles on tenor sax, and drummers Trae Crudup on four studio tracks and Chad Taylor on three live ones, Unknown Rivers sees the band pushing towards greater emphasis on rhythmic acuity, highlighting the different approaches to the music of the two drummers. Settles - a stalwart of the fertile Washington DC jazz scene - plays with a quiet intensity, possessing a sound that reminds of players from a distant past set against a modernist's vocabulary. Stewart is the master of a deep, wide groove that cushions and propels, making every musical situation he finds himself in sound good. The Quietus has called the band "gripping... relies on subtlety and insinuation to register it's uncanny power." The Silt Trio is that magical juxtaposition of playing with raw spontaneity while maintaining the music's intent and purpose.
