Roy Rogers is no cowboy, but he does play country -- country-blues, that is. Best known for his reworking of Delta-blues legend Robert Johnson's oeuvre, Rogers should be (and mostly is) considered the preeminent master of the slide guitar, white-guy division. The San Francisco-based musician absolutely slays with his slide, and he'll bounce sonic shards of brilliant blues off the walls of the Rhythm Room on Wednesday, September 21, when Rogers and his Delta Rhythm Kings visit the club, 1019 East Indian School . Hans Olson is also on the bill. Doors open at 7 p.m. Tickets are $18 in advance, $22 day of show. Call 602-265-4842 or 480-784-4444 or visit www.rhythmroom.com.
