OCTOBER 15

Though the peripherals of race and place would have us think otherwise, only a few degrees separate country from the blues. Knowing this, the Holmes Brothers play music in which it makes perfect sense to hear a lachrymose pedal-steel guitar wail cheek-by- jowl alongside razorish rhythm guitar in the James Brown mode. The brothers perform Friday at 8 p.m. at the Barns of Wolf Trap, 1624 Trap Rd., Vienna. $12. (703) 938-2404. (Mike Dolan)
