In dance-music land, there is an oft-observed phenomenon called “the bass face,” wherein large, warbling basslines are so pleasurably overpowering, they cause an electronic-music lover to crunch up his face due to the pure funk of it all (National Geographic “Raver” special coming soon?). No one is more of a shaman of this wonder than Chicago’s own Green Velvet—the man who brought us such dancefloor devastators as “The Percolator,” “La La Land” and, most recently, “Shake And Pop.” Faces will scrunch doubly tonight at his flawless, techno-weirdo production because the man will be performing said basslines “live” from behind the booth at Smart Bar. Remember when you made god-awful expressions and mom would say, “Don’t do that or it’ll stay that way?” Well, even if that were true, tonight would be more than worth the risk. (Jen Boyles)
