Last year, the National Endowment for the Arts (NEA) proclaimed Carla Bley, 80, a Jazz Master. This year sees the release of her highly-anticipated trio CD, 'Andando el Tiempo' (ECM) with bassist Steve Swallow and saxophonist Andy Sheppard, two leaders in their own right, who have kept this trio functioning for 20 years as Bley's main outlet for her compositions and piano playing.
