Hamir Atwal/Joe Tomino/Mike Sopko

Drummer Hamir Atwal, drummer Joe Tomino and guitarist Mike Sopko will throw down some “improvisational mayhem” tonight on the near westside. (Each musician will also perform electronic instruments.) The trio boasts performance and teaching chops from all over the U.S. Prepare for a thrilling night of surprises-around-every-corner music. (Oh, and Sopko and Tomino hail from Cleveland, and Atwal’s a Berkeley-based Warriors fan, so we will certainly encourage a basketball-themed improv battle at some point in the night.) (Sandy)
