Warren Haynes sat in with rising New Orleans band The Revivalists at New York’s Brooklyn Bowl on Friday night. The group—who recently wrapped-up a tour with Gov’t Mule—invited Haynes out for their original song “Catching Fireflies” and the Dr. Dre/Eminem collaboration “Forgot About Dre.”

The show was part of a busy night at the Bowl that boasted sets from Van Ghost, Damn Right! and Future Rock. Both Matisyahu/AGP keyboardist Rob Marscher and Trey Anastasio Band trombonist Natalie Cressman performed with Van Ghost during their set. Van Ghost’s Jennifer Hartswick performs with Cressman in TAB and Marscher in her own Jennifer Hartswick Band.
