They are great!
I love when musicians from different parts of the world take a genre and mix with musics from their own cultures. To keep it in the same theme I'm going to post some Brazilian bands mixing elements from our music with rock/metal.
Let me star with Machete Bomb, one thing that will grab your attention is the Cavaquinho (instrument usually used for samba and pagode) being played with a lot of effects like if it was a electric guitar and it sounds heavy.
Angra is well know around the world and in my humble opinion Holy Land is one of the best albums they released, specially the song Caroline IV. There are so many different elements and they all seem to stitch together in a way you couldn't expect.
Another great song from Angra is Late Redemption and they got Milton Nascimento to sing the parts in Portuguese who recorded one of the more iconic MPB albums called Clube da Esquina.
Chico Science (RIP) e Nação Zumbi, they are one of the bands that started a cultural movement called Manguebeat.
