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. Inactive during the majority of the pandemic-the longest downtime in their history-they approached this recording with lots of pent-up energy. Guitarist Frankie Broyles, singer/bassist Philip Frobos, and drummer Chris Yonker converted their creative fuel into sharp, driving songs that land immediately, sporting chopping riffs, staccato beats, and wiry melodies.Why does Souvenir sound so sharp? Because each track is a compact unit that stands on its own, reflecting the time and place in which it was created. That's why Omni called the album Souvenir: it's a collection of audio objects, a stash of musical miniatures. Think of it as a family photo album, a binder of rare playing cards, a shoebox holding precious gems.Take "Plastic Pyramid," the first song Omni wrote after coming out of lockdown. 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. (Glaudini sings on two other Souvenir tracks, the first guest vocalist the band has collaborated with). 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.The precision and clarity of Souvenir comes from some new Omni developments.
