Reggae dancehaller Terror Fabulous’ name may be more prominently featured in the advertising for tonight’s show, but vocalist Nadine Sutherland deserves equal credit for their catchy duet, “Action,” which has wowed both the reggae and hiphop worlds. Also part of this bass-heavy extravaganza are Louis Culture, Daffy Screw, Super Beagle, Donovan Steele, and D.J. Superslice. At 10 p.m. at Radio Music Hall, 9th & V Sts. NW. $15-25. (301) 422-6265.
