Charlie Haden - one of the best and most influential bassists in jazz. 76
I was lucky to have seen him perform several times. He had a HUGE sound and was one of the few bassists who could grab and hold the rapt attention of an auditorium all by himself. Also was the bassist on one of the most influential albums of all time: "The Shape of Jazz to Come" (Ornette Coleman). Also recorded in other genres of music, and was even the leader in a country western session!
