If you ever doubt Appalachia's influence, just look at Che Apalache. Based in Buenos Aires, this four-man string band calls themselves Latingrass—a fusion of bluegrass and Latin American musical styles. With tight vocals and a distinct sound, their work reflects mountain cultures from Appalachia to the Andes.

In August, they'll release a new album. Produced by legendary banjoist and multiple GRAMMY-winning artist Béla Fleck, "Rearrange My Heart" will be a testament to musical and cultural exchange. You can actually pre-order it today via the band's IndieGogo campaign.

They're also touring the U.S. this year—from Galax to Anchorage—so if you like this tune, check out Che Apalache's calendar. And let us know if you see them in person!
