System Of A Down are set to make their Rock Werchter debut on Saturday 1 July 2017. Soad are Californians of Armenian origin- and culturally you very much feel and hear this element rooted in the lyrics and music of the band. At times, their lyrics reference the Armenian genocide of 1915-18, when close to one and a half million Armenians were exterminated by the Ottoman regime. System Of A Down also engage musically with many wider social/political themes. Their music contains eastern elements overlaid with echoes of Dead Kennedys, Slayer, Van Halen and Frank Zappa. This results in an exotic and compelling variant of Alt/Rock/Metal. In April 2015 System Of A Down played at the Forest National in Brussels. The concert sold out in only 7 minutes.
