DJ Rekha is your coolest South Asian auntie. When you go to see her, she doesn’t say, “Why haven’t you come before?” or “When did you stop dancing to bhangra?” or even “How long are you planning to moon over M.I.A.?” Instead, she pours you mango lassi in a steel glass and hums a bloodcurdling lullaby about a boy whose hair came down to his knees; when your eyes grow droopy, she hands you a pamphlet about how that boy’s great-grandson grew up and came to New York City to drive a cab, only to vanish into a detention center. Then she unties a thick bundle of vinyl from the end of her sari and pulls you down to her basement. It’s too dark for you to see, but you make out myriad sweaty arms and legs and think you hear Andre 3000, Punjabi MC, and maybe even wheat growing in the fields . Oh yeah, you realize. Bhangra still rules. DJ Rekha spins as part of a special Girl Friday at 9:30 p.m. on the Black Cat’s Backstage, 1811 14th St. NW. $10. (202) 667-7960. (Bidisha Banerjee)
