System of a Down — Toxicity

After making a name for themselves with their self-titled debut, System of a Down reached new heights with their sophomore album, 2001’s Toxicity. Melodic, chaotic, and downright hypnotic, the album expanded the boundaries of heavy music. The frenetic “Chop Suey!” became one of the most bizarre hits of all-time on rock radio (even with Clear Channel temporarily removing it from airwaves after the September 11 attacks), while songs like the crushing title track and the haunting “Aerials” also served to propel the album to multi-platinum status.

Sounding like no other band before them, Serj Tankian’s operatic vocals soar over Daron Malakian’s complex musical compositions, with Shavo Odadjian and John Dolmayan forming a relentless rhythm section. All told, Toxicity stands as one of the finest works of heavy music in the 21st century, if not all time. — S.K.
