Last night Groovatron performed a show at The Canopy Club following moe.s appearance at the Foellinger Auditorium in Champaign, Illinois. Late in the evening, two members of moe. showed up to perform with their fellow Summer Camp alums. Rob Derhak was first up, joining on bass during an extended jam in ‘Bone Diggin’.’ Soon afterwards, Al Schnier added guitar to Groovatron’s ‘What You Are.’ This evening in Chicago, Groovatron will trail moe. once again, performing at the Kinetic Playground, which is across the street from the moe./Disco Biscuits show at the Aragon Ballroom.
