Albert and Emil Mangelsdorff are two brothers who had an important impact on the development of German jazz. Emil studied clarinet at the Hoch Conservatory in Frankfurt, but he is more widely known for his saxophone playing. After he was a member of the illegal ensemble Hot Club, (jazz was banned in Germany at the time) he was imprisoned by the Gestapo and forced into the Hitler Army. After the war he performed in the Frankfurt All Stars and the Jazz-Ensemble des Hessischen Rundfunks before forming his own quartet in the 1960s. Albert is most known for his technique of playing multiphonics. A trombone player, he led a hard bop quintet in the late 50s, and performed frequently with his brother. This release is a compilation of concerts and studio sessions, recorded in the height of the brothers’ career, between 1956 and 1963.
