Difficult as it may be for younger listeners to believe, there was a time when ECM released adventurous improvised music. Back near its inception in the early '70s, the label issued a wide variety and decent number of challenging avant-garde recordings that represented some of the most forward-looking musical thinkers of the time. One of these was Marion Brown, who, at the time of this session, was about midway between his extreme post- Coltrane explorations and the luscious, down-home evocations of Georgia that he would create for Impulse! over the next few years. He gathered 11 musicians, including a couple from the then current Miles Davis Bitches Brew band (Chick Corea and Bennie Maupin), the then little-known Anthony Braxton, Andrew Cyrille, and the late great vocalist Jeanne Lee for two side-long, wide-ranging pieces.
