Although Myron Grombacher has been Pat Benatar's drummer since her second album, Crimes of Passion in 1980, he actually started out as a singer. Though Myron Grombacher admits he was not very gifted vocally, his fellow band mates recognized he was "one heck of a dancer" and therefore the logical choice for frontman. When he was seventeen, Myron Grombacher's band's drummer failed to show up to a paying gig, and Myron took the stool for the first time, and he turned out to be a better drummer. When the band members realized that each earn three more dollars per gig without the absent drummer, they kicked him out and kept Myron behind the kit.

Before hooking up with Pat Benatar's band, Myron Grombacher played with a local bands from Youngstown and Cleveland, and with Rick Derringer. Myron Grombacher also worked on studio albums for Lita Ford and Bob Dylan.

Myron was known for his high-octane showmanship and energetic performance style. Earlier in his career, Myron Grombacher performed "all over the stage." But recently, he stays behind the kit to "communicate a different source of energy." Myron now focuses on the feel and the technical aspects of his music instead of flashy theatrics.

When not touring with Pat Benatar, Myron Grombacher works with the Woodland Hills Drum Club, which raises money for drummers, drum charities, and other charitable organizations.

Myron Grombacher's philosophy on drumming: "You have to love the instrument and [want] to take the instrument and your abilities as far as you can. The primary function of a drummer is to supply time and feel for the band. The drummer has the musical responsibility to the band. If the drummer has a good night, everyone in the band will have a good night."

While he is self-taught, Myron Grombacher recommends that fledgling drummers "find a teacher that will teach you want you want to know, but will also give you a good background in music and theory." Myron admits that he can no longer read sheet music. Now he calls the handicap a functional illiteracy.
