The rocking new persona of Frankie 'Malcolm in the Middle' Muniz should come as a shock to no one - as long as actors have earned a paycheck in Hollywood, there have been some looking for extra work in the musical side of showbiz.

Veteran actors like William Shatner, Hugh Laurie, Russell Crowe and Steve Martin lead double lives as recording musicians. Welcome to the fold, Frankie.
