Vinyl LP pressing. The 3LP-set Uncharted Territories reunites double bassist/composer/bandleader Dave Holland with saxophonist Evan Parker, a longtime friend from their early days in London. They're joined by Craig Taborn, on piano and electronics, and Ches Smith on percussion. In addition to quartet improvisations, they also break off into every possible subset of duo and trio configurations here. Featuring two compositions by Smith and one by Holland, the 23-track collection presents a series of deep, multi-layered conversations between the musicians, some of whom were interacting for the first time.
