When pop quietists the American Analog Set wrote “We’re Computerizing and We Just Don’t Need You Anymore,” the last song on their excellent 2001 release, Know by Heart, most folks probably thought it was some kind of joke. Turns out it was the group’s way of pink-slipping its guitars. The Austin, Texas, band has flirted with electronica in the past, but on its new EP, Updates, it commits full-fledged adultery. Updates gives six AAS songs the “remix” treatment. Remix my ass: “Know by Heart (Her Space Holiday Mix)” is a completely new creature, a dance-floor anthem with a robot’s heart and tweaker feet. On the other hand, “Postman (Styrofoam’s Just Like the Nineties Never Happened Mix)” takes the best song about the U.S. Postal Service since “Please Mr. Postman” and actually manages to improve it. I’m not sure which AAS—the guitar popsters or the electronic warriors—will take the stage. But either way, it’ll be worth checking out. With Her Space Holiday at 9:30 p.m. at the Black Cat, 1811 14th St. NW. $8. (202) 667-7960. (Michael Little)
