While System of a down are often cast with the nu-metal crowd, their sound is closer to '80s thrash (and even hardcore punk) than to any of the rap-metal hordes. Grinding guitars and death-knell drums may be the order of the day, but they work in service of a highly developed socio-political consciousness. In fact, when he's not lacerating his vocal cords, singer Tankian delivers his rebellious lyrics in a tone reminiscent of infamous Dead Kennedys frontman Jello Biafra. Make no mistake, the thrash quotient on TOXICITY is high enough to satiate even the hungriest headbanger, but System of a Down understands the power of dynamics, often moving from a whisper to a scream over the course of the album (though they obviously spend far more time on the scream end of the spectrum). Additionally, they deliver their eye-gouging riffs with an unerring precision that never devolves into an indistinct blur. This hard-hitting quartet knows how to deliver the hard-rock goods with grace.
