SILVER APPLES emerged from New York in 1967 with a rhythmic sound that was too revolutionary for the times. Forty years later, the name still carries a lot of weight among music heads who have an ear for true genius. Silver Apples opted for oscillators rather than guitars. And with these futuristic tools the group surfs the sine waves, carving out deep, psychedelic grooves that are as addictive today as they were when Bob Dylan and the Beatles were young men. The show Mon., JUNE 30, offers a rare live performance from a group that changed the world of electronic music. $12. 9:30 p.m. The Earl, 488 Flat Shoals Ave. 404-522-3950. www.badearl.com.
