Bassist Josh Abrams' quartet embodies a devastating geographic cross section of today's free music. Abrams started in Philley's The Roots and went on to Chicago's Town And Country and the David Boykin Expanse. Jeff Parker is well known for his work with Tortoise, Chicago Underground and his first album as leader, Like-Coping (Delmark 543). Guillermo Gregorio's work spans a lifetime of improvised playing with Fred Lonberg-Holm, Jim O'Rourke and Anthony Braxton to name just a few. Axel Dorner's output as both free improvisor and composer cover multiple continents with John Butcher, Alexander von Schlippenbach and Mats Gustafsson.
