Partially atoning for the basically unforgivable sin of actually requiring everyone who wants to go to next week’s Roots/Drake/Passion Pit Webster Hall extravaganza to wear hideous Diesel jeans in order just to receive an invitation to damn thing, Diesel is also hosting free shows at their NYC store this week. Today’s band? The excellently fresh NYC disco collective The Phenomenal Hand Clap Band, whose low-key and tie-dyed rave downs should make a curious musical accompaniment to the normal work-wage suicide trudge of uptown’s 5th Avenue and 54th Street. The free show is at 3pm, and seems to require absolutely nothing in the way of pre-washed and randomly patterned downscale-upscale denim. Recommended. Also, tomorrow, they’ve got a vertible CMJ showcase in there, starting at 2pm: Black Gold, Elevator Fight, Here We Go Magic, and most incongruously, a twilight spin, circa 7pm, with the afghan-blanket clad sub-Yeasayer Brooklyn quartet Suckers. Hey, it’s your Friday night.
