It's always kind of cool to see a band step out of their element. Brazilian headbangers Sepultura make some of the most aggressive metal out there, but here they are doing a beautiful acoustic version of U2's 'Bullet the Blue Sky' on a Chilean TV show. Sepultura is currently doing a South American tour with Machine Head, and their latest album Kairos came out last summer. If you speak Spanish, you'll also be able to understand the interview. If not, enjoy the song.
