Always interested in music, Toth says he's been drumming most of his life. He made good use of his father's record collection and was active in all music programs in East Lyme, Connecticut, playing in his high school band at East Lyme High School. He went on to the University of Miami's Frost School of Music, where he received a Bachelor of Music degree in 1994. While still at school, Toth became a member of the funk/rock band Jennifer Culture.
Toth has played in numerous other rock and funk bands over the last decade. Most notably, he was a member of Vertical Horizon from 1996–2005, which yielded a multi platinum album "Everything You Want", the title track of which also charted #1. Toth's association with the group began when he was working at a BostonBorders Books; Matt Scannell's mother came into the bookstore, asking for a Vertical Horizon CD. In gratitude for the assistance she received at the store, she offered to put the bookstore manager and a friend on the guest list for a Vertical Horizon show at Mama Kin. Toth went to the show as the manager's friend; when the band had an opening for a drummer, Toth auditioned for the spot.
The Doobies' drummer, Keith Knudsen, died of cancer in 2005; Toth was selected to fill his spot with the band. Toth has also produced some critically acclaimed albums and started a band called Cooper with his friend, Tim Bradshaw.
