D.C.’s Frank “Scooby” Sirius—best known for playing guitar with a credit card as a pick and singing with groups like the Chuck Brown Band and Team Familiar (formerly Familiar Faces)—has also spent the last six years developing his own R&B career. This godson of go-go’s 2009 cut “Remember My Name” made the Billboard R&B/hip-hop chart; his cover of Bob Marley’s “Is This Love” is out now; and he’s also recording an album of his own material. Sirius’ voice sounds polished and friendly enough for pop, but he can soulfully wail in earthy, old-school tones just as well as he climbs the scales with his falsetto. Sirius really shines on versions of Donny Hathaway’s “For You” and the Spinners’ “How Could I Let You Go Away.” For this gig, Sirius will be joined by a band that includes keyboardist Marcus Young and drummer Kenny “Kwick” Gross from the Chuck Brown Band. While the emphasis will be on rhythm and blues, Sirius says he may include a few percussive go-go numbers to get his fans out of their seats and shaking. Frank “Scooby” Sirius performs at 8 p.m. and 10 p.m. at Blues Alley, 1073 Wisconsin Ave. NW. $25. (202) 337-4141. bluesalley.com.
