German trombonist Albert Mangelsdorff chose the trombone because he felt it came closest to the sound of the human voice. He amplified this idea with multiphonics – play one tone, sing another, thereby creating chords. His use of multiphonics broadened the possibilities of the instrument, and his playing catapulted Albert onto the international stage. His solo album Trombirds is a demonstration of multiphonics in full flight. Blues Of A Cellar Lark digs deep into the lower range of the horn, alternating between harmonics and a free-singing open horn sound. This lark’s something of a blues bird. Trombirds sounds like a whole flock as Mangelsdorff plays with multiphonics, lip trills, double tonguing, and all sorts of vocal antics to achieve sounds that must be heard to be believed. Yellow Hammer hits hard with a rock-pop feel and some pyrotechnic phrases that will stun the listener. Introducing Marc Suetherlyn is the only piece with overdubs and playbacks, and at times it sound like a brass orchestra. The Spanish elements in Espontaneo developed spontaneously, and have the ring of Flamenco. The ballad Sing A Simple Song For Change contains the beautifully played and sung message of the whole album. A must for Mangelsdorff fans as well as any music lover who wishes to hear a master innovator at his solo best.
