Petty Or Not has been performing faithful renditions of the music of Tom Petty & the Heartbreakers throughout California and the Las Vegas area since 2013, providing their audience with a true live Tom Petty experience. Following the tragic loss of Tom in October of 2017, PETTY OR NOT was selected to be the house band for the Musicares Memorial Show at the Regent Theater in DTLA, and PETTY OR NOT vocalist Erik Szabo performed at Mary Sorcco's Vampire Walk in Sherman Oaks, which has now become an annual event honoring Tom Petty.
