New grass all-stars, Greensky Bluegrass hit up The Fillmore Philadelphia earlier this week. Joe Russo’s Almost Dead member and frontman of The American Babies, Tom Hamilton joined GSB for a few tunes while in Philly.

Hamilton sat in for a total of three songs including “Butcher Boy” and “Demons” as well as a cover of the Grateful Dead‘s “Mr. Charlie.”
