Charlie Haden is one of the foremost bass players in contemporary jazz. In the 1950s Haden was a part of the first Ornette Coleman Quartet, which was the center of a jazz revolution. He has been involved with both avant-garde and mainstream jazz ever since. In the 1960s he formed the Liberation Music Orchestra, whose pointed political references were controversial. Haden has recently re-formed the Orchestra and also plays with the band Old and New Dreams, made-up of Coleman alumni. He has also recently recorded an album with Denny Zeitlin.
