Already somewhat of a supergroup composed of ex-Screaming Trees drummer Barrett Martin, R.E.M. guitarist Peter Buck, and longtime R.E.M. compatriot/Young Fresh Fellow/Minus Fiver Scott McCaughey, the sprawling collective that is Tuatara is about to get even more super-duper. June will bring the release of Tuatara's latest album, East of the Sun, on Fast Horse Recordings. Guests on the album are plenty. Dean Wareham lends his unmistakable pipes to two tunes. Other vocalists that show up on the album are Mark Eitzel, John Wesley Harding, Victoria Williams, Mark Olson, Gary Louris, Jessy Greene, and Gina Sala. There are even two spoken word pieces featuring Sufi poet Coleman Barks. Fast Horse has most of the songs available for your listening pleasure here.
