William "Billy' Sheehan" (born on March 19, 1953, in Buffalo, New York) is an American bassist known for his work with Talas, Steve Vai, David Lee Roth, Mr. Big, and Niacin. Sheehan has won the "Best Rock Bass Player" readers' poll from Guitar Player Magazine five times for his "lead bass" playing style. Guitar Player has likened his soloing on the four-string instrument to Eddie Van Halen's on the six-string guitar. Sheehan's repertoire includes the use of chording, two-handed tapping, right hand "three finger picking" technique and controlled feedback. However, Sheehan is also noted as a steady "true" bassist, fulfilling the traditional supportive role of the electric bass in the rock rhythm section. He has been a member of the Church of Scientology since 1971 and appeared on the street offering to defend it during Project Chanology.
