Despite a wealth of samples from both sides of the East/West divide, Cornershop’s music sounds less like Punjabi hiphop than the Fall possessed by Kali. This British quartet claims as its subject matter all of Anglo-Indian culture, from Jason Donovan and the Smiths to sitars, curries, and a wide variety of “language problems.” The viewpoint may be subcultural, but the groove is bigger than the subcontinent. The band opens for Medski Martin & Wood at 10 p.m. at the 9:30 Club, 815 V St. NW. $10. (202) 393-0930. (MJ)
