Monsters of Rock was an annual rock music festival in England held every August at the Castle Donington racetrack from 1980-1996 (with the odd exception, and a one-off comeback in 2006). Monsters of Rock festivals have also been organized in other cities around the world. After the success of Monsters of Rock 2006 there were suggestions for a Monsters of Rock 2007 but the show appears to have been cancelled as rumours have died down
