On the Blakes’ upcoming record, a self-release called Souvenirs that comes out October 13, the Seattle trio’s tweaked the jumpy rock and roll songs they’re known for and slowed them down into sultry, messy songs that sway instead of bounce — like “Basket” or “Magic,” which sounds like some forgotten Beatles B-side. Not that they’ve abandoned the frantic adrenaline-shot numbers that get the kids thrashing around like people possessed — there’s plenty of that, and it’s awesome — but the band’s also ventured into much poppier territory with success. These guys know how to write a hook, but it’s Garnet Keim’s gravelly way of crooning sweet little nothings that makes the Blakes so easy to love. When he sings, “Hey there, Juicy Fruit. Take off those diamond shoes,” on “Charmed,” it’s obvious that the Blakes’ grungy, grimy rock and roll sensuality is the real secret to the band’s success. With the Purrs, Strong Killings.
