Drummer David Lauser grew up in California, where he first learned how to play the drums after becoming enamored with the emerging rock music from Britain in the early '60s. During his teens, Sammy Hagar (who was also quite young) sat in with his band and they performed together until a move to San Francisco matched Hagar with Ronnie Montrose. He separated from Lauser to perform in Montrose, but Lauser continued to perform as a solo artist and in several bands. Hagar produced a demo for one of these bands when he noticed how strong his former drummer still played, so he picked him to drum in his band during his first solo outing. The two performed together until fate again separated the two and Hagar was asked to join Van Halen. Lauser continued to perform and eventually the split between Hagar and Van Halen led to their professional reunion. Lauser continued to play with Hagar into the next decade, even joining him on the unusual co-headlining tour with David Lee Roth in 2002.
