If you dig the sound of an electric guitar slicing through a prickly pop-rock song, Omni is your new favorite band. No joke. The Atlanta trio’s debut full-length Deluxe—released in July on Trouble in Mind Records—is a compact collection of catchy post-punk songs with sharp corners and stony attitude. Drummer Billy Mitchell pushes Omni along like a laser-guided rhythm robot. Philip Frobos’ basslines snap like a rubber band stretched to its limit, and his dead-eyed vocals ably straddle a line between memorable and amelodic. Each member is a vital part of Omni’s admixture. But it’s Frankie Broyles’ guitar—sharp, jangling, rubbery, and weird—that puts Deluxe into a higher sonic tax bracket. His sound should be bronzed and inducted into the Post-Punk Hall of Fame. Joining Omni on tonight’s bill are globally-inspired experimental locals Alto!, whose excellent LP3 also came out on Trouble in Mind earlier this year. BEN SALMON
