If that doesn't work correctly, try this link, or just skip to 15 minutes and 30 seconds into the video. That's when the song starts. They're a Brazillian thrash metal band, and the middle is raging metal stuff, but don't worry, it turns pretty again at the end, with some flamenco guitar even sneaking in there. The skill level is crazy.
Another surprising moment from Brazillian metal is this bit of "folk metal" (far more folk than metal -- and they sound more Irish than Brazilian). The guest singer is Fernanda Lira from Nervosa. She usually screams like an angry cat (which I also like), but can also verge on Aretha Franklin when she wants to sing "clean."
As much as I love her regular band, I wish she'd do more clean singing, too. Since she and the guitarist are both really into blues, I'm hoping they'll start a side project.
