April 19 street date. Atrás del Cosmos were a central force in Mexico City's creative arts community, and often considered the first free jazz group in the country. Founded by a trio composed of pianist Ana Ruiz, percussionist Evry Mann, and saxophonist Henry West, the ensemble was prolific in mentoring a generation of improvisers, cultivating an expanded additive roster, and organizing workshops in downtown Mexico City - including inviting Don Cherry to play and instruct on his "organic music" approach in 1977. Despite their central importance to the local scene, Atrás was rarely recorded and had a scant international presence, leaving behind just a single cassette before their disbandment. Now issued on LP for the first time, "Cold Drinks, Hot Dreams" is a red-hot recording documenting the core group plus double-bassist Claudio Enriquez performing live in 1980 - a delirious improvisation with high peaks and low valleys, sucking in an amalgam of influences including New York loft style, Mexican folk music, and the surrealism of Alejandro Jodorowsky into its heady gravitational pull.
