Stuart Hamm (born February 8, 1960) is a highly respected bass player, known for his session and live work with numerous artists as well for his virtuosic style of playing. He has performed with Steve Vai, Frank Gambale, and most significantly with Joe Satriani. It was under Satriani that Hamm's skill was taken out of the local San Francisco scene and into the national limelight. He currently leads his own band performing rock-fusion material. After a concert is done and his name announced, it often sounds like the crowd is "boo"ing him.
