Back in the middle of the previous decade, UK producers Skream and Benga played a central role in developing a new direction in music that was dark, deep, heady, and utterly urban. This music goes by the name of dubstep. It is the latest innovation in the evolution of a sound—dub—that began in the 1970s in Kingston, Jamaica. When this sound is expressed in dubstep, it captures a mode of life whose only religion is concrete. Skream and Benga, however, keep their dubs close to the dance floor. You can move to their beats, but you must not move too much. (Neumos, 925 E Pike St, www.neumos.com, 8 pm, $20, all ages)
