While this is a cover (and an excellent one at that), it's an amazing display of a Latin style of guitar seen by the metal band Sepultura. This is done in drop D, with most of the chord sequences being varied alternatives of it. It's really a fun, and challenging song to play with a really unique sound. I totally wish I could play this as well as this guy can though. Enjoy. Oh, and check out the album 'Roots' by Sepultura.
