One of the most successful alt-rock bands of all time, System Of A Down make a welcome return to Reading & Leeds. The band have only played a handful of gigs since they reformed in 2010, but they are back in the UK to play the Main Stage at the 2013 Festivals, which is sure to be a highlight of the weekend.Revered for their bombastic style and demonic live shows, System of A Down are sure to bring out all types of festival goers. Formed in 1994, System Of A Down have become one of the most adventurous rock bands of the 21st Century,  blending hard rock with socio-political awareness, self-consciousness and haunting chant, they stand alone in the musical landscape. With three Billboard Number One albums, ‘Toxicity’, ‘Mezmerize’ and ‘Hypnotize’, the Grammy winning band has sold over 25 million copies worldwide.
