The jazz community is mourning the passing of one of its great innovators. Jazz bassist and composer, Charlie Haden, died on Friday, July 11, in Los Angeles. He was 76 years old. His contributions to jazz are immeasurable and his resume is enormous. Charlie never quite settled into any one jazz niche. On one hand, he was a pivotal figure in the birth of the free jazz movement. On the other, he made recordings that drew on traditional American folk music.
