Brujeria.
Catchy, groove-oriented death metal. Spanish growls so over-the-top it'll have you on the floor in tears. Lyrics so blatantly anti-American, anti-White, misogynistic, and politically incorrect you'll mess your pants. And all with the razor-sharp finesse of Fear Factory, and not the noise of A.C.
Puya don't have growls per se, but the singer's voice can be semi-brutal at times. And they mix in rap, salsa, samba, and traditional hard rock solos. They do sing in English as well.
