With a lifelong passion for music, Tommy found his love for bass guitar at an early age. First learning to play the bass guitar by ear, inspired by the musicians he admired. Without any formal lessons, he joined his school bands in junior high and high school playing at school dances and solidifying his love for performing.

In his early 20s, Tom formed a three-piece band with friends, performing at local coffee houses and restaurants in Walnut Creek, CA. This was his first experience as a paid musician, which led to gigs throughout the SF Bay Area. During this time Tom met and played with Doug Clifford ("Cosmo"), the drummer for Creedence Clearwater Revival.

In his 30s Tom began a decade-long journey touring with the Gregg Allman Band (1994-2004). This experience was incredibly instructive and solidified his passion for performing at a professional level. During this time Tom was invited to join the Alameda All Stars.

Inspired by a wide range of musicians, including bassists like Rick Danko (The Band), Paul McCartney (The Beatles), and Chris Squire (Yes). as well as vocalists such as Don Henley (The Eagles) and Paul Rodgers (Free and Bad Company) Tom’s musical taste expanded, spanning many genres, from Led Zeppelin to John Prine, and Joni Mitchell to Joe Jackson.

Bob began playing and recording music at age five, becoming a church organist by 13. Influenced by innovative keyboardists like Gregg Rolie (Santana), Jan Hammer (Jeff Beck), and Tony Williams (Tony Williams Lifetime band).

Bob enjoys a wide range of music, often going through phases of different styles. His professional journey began after graduating from Sonoma State University, when he joined the R&B and soul band The Value Kings, playing extensively throughout California for five years in the 1980s. He then joined Gamma with Davey Pattison, evolving from a duo to an 11-piece band. For the next two decades, he played with various Bay Area bands, including a church gig as a pianist.

From 2010 to 2023, Bob played with the R&B blues soul singer and guitarist Levi Lloyd, a collaboration he greatly enjoyed. After Levi's passing in 2023, he formed The Workshop, adding a saxophone to the mix, and continues to play gigs in the Bay Area.
