Fronted by local singer-songwriter Thad Cockrell, brand-new pop-rock outfit Leagues clearly has a mind for the arena. Their debut EP, fittingly monikered Summer EP, features grandiose vocal melodies, ambitious arrangements and the sort of feel-good imagery about broken hearts in romantic locales — deserts and Midwestern fields and so forth — that says, “We intend to play really big venues before too long.” But before you think Leagues are shooting for the same terrain as, say, Kings of Leon, know this: Yes, it’s somewhat sentimental and intentionally heartstring-tuggy, but the production on Summer EP — which was engineered by Third Man Records’ in-house sound dude, Vance Powell — is idiosyncratic and genuinely interesting, riddled with horns, glockenspiel and other subtle embellishments. Yeah, it’s somewhat saccharine, unabashed pop rock. But that’s what they’re going for. Plus Cockrell’s voice is about as immaculate as they come. Come September, Leagues will be jumping on as support for Mat Kearney’s tour, which will bump them up to mid-sized clubs like Cannery Ballroom. See? They’re already on the warpath for bigger venues.
