Double vinyl LP pressing. Expanded edition. Revisited and remastered, with additional takes, texts and photos, here is the very first ECM session, recorded in November 1969, featuring the great American pianist Mal Waldron, whose resume included work with Coltrane, Mingus, Dolphy and Billie Holiday. As Jazz Journal noted, "the music sounds as fresh now as the day it was recorded". Indeed, the tersely-grooving "Boo" and "Rock My Soul" could be club hits half a century later.
