This edition of Sound will feature the original Stu Black mix, previously unissued on CD, the original J.B. Figi liner note and new notes by Delmark's new Artistic Director Elbio Barilari. Sound - a landmark recording! Sound - the first documentation of AACM music! Sound - the state of the art of ensemble in 1966; a summary of the past and implications of things to come! Sound received a five-star rating in Down Beat's June 15, 1967 edition."Mitchell, the AACM's greatest player and composer, is in brilliant form, as are his Art Ensemble of Chicago colleagues Lester Bowie and Malachi Favors and the others. A new chapter in what Chicagoans like to call 'Great Black Music.'" - Rolling Stone
