Since releasing their Mercury Award-winning debut album An Awesome Wave last year, the U.K.-based indie rock band Alt-J have embarked on sold-out tours, topped the alternative music charts, appeared at Coachella and Bonnaroo and played a set with the Flaming Lips at SXSW. Now the rockers are back on an extensive countrywide tour to promote An Awesome Wave.
Here, get an exclusive first listen to the band's acoustic version of "Bloodflood," originally released as a single in 2011. The acoustic track replaces the original's heavy and constant beats, eerie children's chants, and extra effects with just fluttering piano and smoother, slower vocals. The only driving beat lies in a cappella-esque vocal portions for an affecting result.
An Awesome Wave is available on Canvasback/Atlantic.
