Doppelgang3r Presents Chop Suey + SlipNOT + The Violent Inzident. The ultimate tribute showdown. CHOP SUEY—Europe’s biggest tribute to System of a Down—recaptures the raw energy of SOAD’s early 2000s with members of Dragonforce, Anti-Nowhere League, ex-Breed 77, and TigerTailz. Slip-NOT—the UK’s premier Slipknot tribute act—brings the ferocity of Slipknot. The Violent Inzident kick off every show as the best nu-metal band since Five Finger Death Punch. 8+ (Under 14s accompanied by an adult).
