Through his innovative work as a solo artist and his contributions as a sideman to Joe Satriani and Steve Vai, Stuart Hamm has firmly established himself as one of the most influential electric bassists of the past half-century. Extending the non-traditional function of the electric bass previously revolutionized by Jaco Pastorius and Stanley Clarke in the 1970s, Hamm helped to reshape the contemporary concept of the bass guitar as an unaccompanied instrument with the utilization of polyphonic, two-handed tapping, slapping and popping techniques, chords, and harmonics.
