System of a down (SOAD)

The band was formed in 1994. It was made by Serj Tankian, Daron Malakian, John Dolmayan and Shavo Odadjian. They are American people, but their parents came from Armenia.

They have 5 albums: 
System of a Down(1998)
Toxicity (2001)
Steal this Album (2002)
Mezmerize (2005)
Hypnotize (2005)

In 2006, they rid the group. Serj Tankian made her own band, just singing and playing the piano. Daron and Dolmayan made another band, called Scars on Brodway. And finally, on 2011, SOAD joined again, but only temporally.
