Alt-J

Alt-J

Gabriel Green

Alt-J's new single "Left Hand Free" is the British group's most brazen rocker to date, and the official music video accordingly captures the raucous spirit of summer, with an Americana twist.

Directed by Ryan Staake, the "Left Hand Free" was filmed on the Guadalupe River outside of Austin, Tex., and showcases a handful of college-aged kids shooting off fireworks, tubing down the river, lazily riding bikes shirtless and eventually reconvening later that night for some summertime romance. Everyone in the clip is generally having fun, while Alt-J sounds like they are also having a blast stepping away from art-rock to get down and boogie.

This Is All Yours follows Alt-J's Mercury Prize-winning debut album An Awesome Wave, and is set for release on Sept. 23. "Left Hand Free" is the second song released from the album, following the Miley Cyrus-sampling "Hunger of the Pine."
