Albert Mangelsdorff (September 5, 1928 – July 25, 2005) was one of the most accredited and innovative trombonists of modern jazz who became famous for his distinctive technique of playing multiphonics. Mangelsdorff was born in Frankfurt, Germany and had violin lessons as a child and was self-taught on guitar. His brother, alto saxophonist Emil Mangelsdorff, introduced him to jazz (which was forbidden in Germany during the Nazi time) After the war Mangelsdorff was working as a guitarist and took up trombone in 1948.
