This rare 1963 recording showcases the incredible early work of German trombonist Albert Mangelsdorff and his quintet. Featuring Heinz Sauer on tenor saxophone, Gunter Kronberg on alto saxophone, Gunter Lenz on bass, and Ralf Hubner on drums, the ensemble creates a groundbreaking modernist groove comparable to the innovations of Ornette Coleman and Joe Harriott. The absence of piano and the three-horn frontline contribute to a bracing and powerful sound, striking a dynamic balance between freedom in horn solos and a tight rhythmic foundation.
