The music of Atlanta trio Omni has always swung fast and hit hard. And Souvenir, their fourth album and second for Sub Pop, packs their biggest punch yet. Frankie Broyles, Philip Frobos, and Chris Yonker converted their creative fuel into sharp, driving songs that land immediately, sporting chopping riffs, staccato beats, and wiry melodies. Take “Plastic Pyramid,” filled with twists and turns, it’s a journey unto itself, charged by clanging chords, spinning rhythm, and Frobos trading lines with Izzy Glaudini of Automatic, with whom Omni toured with last fall. Or take opener “Exacto,” a slicing web of intertwined guitar and bass. Its razor-fine notes and syncopated beats perfectly match pointillist Frobos lyrics such as “Exacto, de facto, concise, quite right”–a line that could well be an Omni mantra. You might notice that Frobos’ singing is a bit more emotional and even nostalgic this time around. In crafting his vocals, he was inspired by the formative favorites like REM, the Cure, and Big Audio Dynamite–the kind of bands whose melodies could have been top 40 hits in an alternative universe. Immediacy rushes throughout every moment of Souvenir, their most powerful album to date.
