An anxious person’s nerves are always firing, resulting in involuntary twitches, and Chicago’s Nerves are as jittery a rock band as they come. Wire-y melodies, Gun Club-like tales from the dark side, and garage rock’s teenage fire are scrunched together on Nerves’ second long-player, New Animal, an absolute finger-in-the-air salute of a rock ‘n’ roll album. There isn’t a lot of punk music being made that sounds so convincingly as if it’s from another era, but Nerves touch on all that was so energizing about the likes of Radio Birdman and Television. Singer-guitarist Rob Datum yelps his words and bends his trebly strings as bassist Seth Skundrick menaces the low end and drummer Elliot Dicks beats his kit like a psychotic hopped up on greenies. Live, the band is supposed to be even snottier than it sounds on its recordings. I can’t wait. With Axis Set at 8:30 p.m. at the Black Cat, 1831 14th St. NW. $5. (202) 667-7960. (Christopher Porter)
