One of the things that makes SYSTEM OF A DOWN stand out is frontman Serj Tankian‘s unique vocal approach. His incredibly wide range fuels the band’s drastic tempo and atmosphere changes to become a reality. The band’s most commercially successful song, “Chop Suey!” is a prime example of his outlandish vocal delivery, is taken from the group’s sophomore album, “Toxicity”, which was released in 2001. It debuted at No. 1 on the Billboard Top 200 chart, selling 220,000 copies in its first week. The album remains a staple among modern metal fans and beyond.
