“Indie.” “Rock.” Do those two words mean much of anything when used in tandem anymore? Back in the ‘90s, they meant a few things. They meant jagged, angular guitars, a sense of urgency, telling lyrics, post-punk and classic-rock influence, and a commitment to cranking out records even when it felt like basically no one was paying any attention. “Indie rock” meant bands like Silkworm, Seam, Pavement, Chavez, Guided by Voices, Dinosaur Jr. and virtually everyone on Matador Records. Local three-piece Ocelots have long been keeping the ‘90s tradition alive, channeling the raw guitar work and math-y time signatures of the aforementioned trailblazers. Their latest five-song EP, Satan’s Darts, features all the indie-rock conventions we 24- to 36-year-old audiophiles tend to flip our lids over, plus a little bit of nuance: The rich organ part and Pavement-esque beat of “Breaking With the Patriots” alone make this EP worth your time. Last time Ocelots hosted a record release at Grimey’s, there were tons of free beer and cookies. No reason to think that won’t be the case again this time.
