System of a Down, also known by the acronym SOAD and often shortened to just "System", is an Armenian-American rock band from California. Rock may be a lighter description, as much of their music is more like Metal. The bands members are Daron Malakian, Serj Tankian, Shavo Odadjian and John Dolmayan. All four members are of Armenian descent. Although their song lyrics include some references to drugs, sex, and other controversial subjects, the core of the subject matter revolves around bringing attention to the Armenian Genocide of 1915. Many of their songs also include views on political issues such as The War on Terrorism.
