On a recent Thursday evening, about 80 people gathered in a room in Crosstown Concourse flanked by dark green curtains and ringed with sofas, love seats and armchairs. Amber light glowed from assorted lamps on side tables.

Standing on a rug in the room’s center, twin brothers Christian Underwood on bass and Christopher Underwood on drums, known as The PRVLG, played with Paul Taylor.

The concert was part of The Groove music series, focused on “funky bands,” at The Green Room, one of four music venues operated by Crosstown Arts. Other sites include Crosstown Theater, the East Atrium and 430 N. Cleveland, across the street from the Concourse.
