MACHINE HEAD One of the more intriguing metal bands on the circuit, Machine Head’s menacing thud is colored of late with classical and Latin guitar shadings. For almost two decades, the quartet has churned their grind and thrash apropos to the genres, but they’re always looking forward and aren’t afraid to delve into experimentation and epic songcraft while continuously evolving and honing their chops, singing melodically even. That’s not to say the thunderous percussion and blasting guitars won’t frighten the neighbors. With Suicide Silence and Darkest Hour. (Samir Shukla)
