For the mountains of jangly, lo-fi pop its released over the years, Teenbeat more than deserves its own night at the Black Cat. This Saturday, the Arlington-formed, Cambridge, Mass.-based label celebrates 26 years of four-tracks and 7-inches. Label co-founder Mark Robinson will be leading the pack with three incarnations of his prolific band Unrest, which broke up in 1994. It’s a chance to witness in one evening a decadelong progression from noisy experimentalism to sparse, poppy post-punk. There’ll also be the grungy indie rock of New York trio Versus; the feedback-laden doo-wop of D.C.’s Rondelles; and the psych-inflected pop of Vancouver’s Bossanova. And while the short-lived Justin Chearno era of Unrest won’t be represented, there’s no way the group will skip “Yes She Is My Skinhead Girl.” Right?

THE CONCERT TAKES PLACES AT 8 P.M. AT THE BLACK CAT, 1811 14TH ST. NW. $15. (202) 667-4490.
