Charles Haden is a jazz double bassist, probably best known for his long association with saxophonist Ornette Coleman. Haden is also known for his signature lyrical bass lines and is one of the most respected jazz bassists and jazz composers today.
Haden became famous playing with Ornette Coleman in the late 1950s, perhaps culminating with “The Shape of Jazz to Come”. He went on to lead the Liberation Music Orchestra in the 1970s. Largely arranged by Carla Bley, their music was very experimental, exploring the realms of free jazz and political music at the same time; specifically, the LMO’s first album focused on the Spanish Civil War.
In 2005, Haden reconvened his Liberation Music Orchestra, with largely new members, for a new album, released Verve Records, called “Not In Our Name”. The album dealt primarily with the contemporary political situation in the United States, and was the first appearance of the orchestra since 1990’s “Dream Keeper.”
