is an American rock band formed by musicians of Armenian origin: vocalist Serj Tankian, guitarist Daron Malakian, bassist Shavo Odadjian, and drummer John Dolmayan in the mid-1990s. They have released five studio albums, seventeen singles, and eleven music videos. By the end of 1997, the group had signed to American Recordings, then distributed as Columbia Records. The following year, they released their eponymous debut album, which peaked at number 124 on the United States' Billboard 200 and number 103 on the United Kingdom's UK Albums Chart; it was certified platinum two years later by the Recording Industry Association of America , and gold by Canadian Recording Industry Association . Their eponymous debut album produced a single for the song "Sugar", which reached the top 30 on the Billboardmainstream rock songs and alternative songs charts. Their follow-up album, Toxicity , topped the US and Canadian charts, and also reached the top 10 in Australia, Finland, and New Zealand. The album was certified triple platinum in its home country, and triple platinum in Australia by the Australian Recording Industry Association, as well as double platinum by CRIA in Canada. Toxicity produced singles for the title track, "Chop Suey!", and "Aerials". The last of these peaked at number one on the BillboardMainstream Rock Songs and Alternative Songs charts. Steal This Album! failed to repeat the same success as its predecessor, reaching the top 20 in only the US and Australia. Three years later, the group produced a double album, with the two sections released six months apart. The first, entitled Mezmerize, was released in early 2005; it peaked at number one in nine countries, and certified triple platinum in Canada, platinum in the US and Australia. This album's first single, "B.Y.O.B.", peaked at No. 27 on the Billboard Hot 100 and No. 26 on the UK Singles Chart. The follow-up, "Question!", reached the top 40 in the United Kingdom and Ireland. Later that year, the group released the second part, Hypnotize. Like its predecessor, the album peaked at number one in the US, Canadian, Finnish, and New Zealand charts. System of a Down is the first band since The Beatles to release two chart-topping albums in the US in the same year. Hypnotize was certified platinum in US, and gold in Australia, Germany, and Switzerland. It produced two singles, the title track and "Lonely Day", which reached No. 4 and No. 16 on the Finnish chart, respectively. In 2006, the group went on a hiatus, and since then, all members had begun work on side projects. A reunion was announced on November 29, 2010, and according to drummer John Dolmayan, there may be a new album.
