World-class drummer Pat Petrillo combines a deep sense of groove and feel with uncanny technique, phrasing, and musicality. Over the years, Pat has backed such artists as Gloria Gaynor, Patti LaBelle, and Dee-Lite.  His latest fusion/funk group, Groovallegiance, features bassist Gary Grainger and guitarist Chieli Minucci. His versatility has also led him to gigs with numerous Broadway shows over the years, including original productions of A Chorus Line, Grease, and Footloose, as well as the national tour of Dreamgirls. As an educator, Pat is a faculty member at the Drummers Collective in NYC, and is one of the most sought after clinicians in the business.  He has released two highly acclaimed instructional DVDs. Learn to Read Rhythms…Better! (Alfred Music), has become the industry standard for teaching rhythm reading. Hands, Grooves, & Fills (Hudson Music), is the first play-along reading DVD and features a 100-page eBook and mp3s.
