Like the vinyl they use as instruments, DJs have largely gone underground. But the resurrection of old-school values in hiphop and the rise of club culture have re-elevated the DJ to his prime position. The nearly decade-old X-ecutioners are one of the best cutting crews around—as they proved by winning the ’95 DMC World Championship and the International Turntablists Federation belt in ’96, and as they wickedly display on their debut album, X-pressions. But unlike their West Coast friendly-rivals Invisibl Skratch Piklz, who usually tear it up on the avant-garde tip, the N.Y.C.-based X-ecutioners flip between the extreme (or is it X-treme?) and the balanced with their frequent use of guest MCs. See the DJs talk with their hands when X-ecutioners open for Common with Rahzel at 7:30 p.m. at the 9:30 Club, 815 V St. NW. $15. (202) 393-0930. (CP)
