With 2009′s Columbus’d The Whim, Holiday Shores crafted a sweeping, breezy sound that went hand-in-hand with the band’s roots: an indie rock band from Florida. But “Airglow,” the opening track for their sophomore set New Masses For Squaw Peak, introduces extended synths and tribal drums, coupled with chillwavey pangs of nostalgia and romance. With its wobbly sonics and numerous textures, there’s more of a rhythmic Brian Eno oozing out — a different sort of breeze, for a song that evokes an airy, glowing feeling.

Yet the subject matter isn’t breezy at all, as we’re told by Holiday Shores principle Nathan Pemberton. “It’s most likely about that moment when a radioactive device goes off and you can see the bones in your hand as you’re raising it to block the holy glare eating the sky,” he says. “[The United States” would shoot missiles into space in the sixties but they would have a nuclear payload, the radiation would circle the planet in belts, disabling satellites, falling to the earth to earth in what I imagine to be a misty haze where it’d reside in the seaweed and float in the ocean.” The more you know.

New Masses For Squaw Peak is out September 13 on TwoSyllable Records.
