Known as the “Angry Man of Jazz,” Charles Mingus utilized group improvisation as well as classical techniques to create lasting performances and recordings that easily contend with the greatest works of more popular innovators such as Davis and Hancock.  Among his best reviewed albums are the classic ‘Mingus Ah Um’ and masterpiece ‘Black Saint.’  Mingus worked with jazz giants including Duke Ellington, Charlie Parker, and Eric Dolphy over the course of a sprawling career.
