“Haven’t I heard this before?” has been the general City Paper office reaction to Number One Cup’s Possum Trot Plan. That’s because this Toddlin’ Town trio features more indie reference points than a convention of fanzine editors: the arch playfulness of Pavement, the attention-deficit disorder song-lengths of Guided by Voices, the sublimely melancholy, catchy riff-rock of Superchunk, yadda yadda yadda. Now insert the requisite, “but the group blends its record-collection rock into a style all its own” disclaimer, because it’s absolutely true. Trot consists of 20 lo-fi, shambling, and utterly captivating tunes, with not a dud among the bunch. It’s been a long time since I’ve referred to something as both “shambling” and “lo-fi” without finishing the sentence with the word “crap,” but Number One Cup reminds me why I liked indie music in the first place. The band plays with Canadian Hüsker Dü aficionados Eric’s Trip and Jimmie’s Chicken Shack at 9:30 p.m. at the Black Cat, 1831 14th St. NW. $6. (202) 667-7960. (Christopher Porter)
