Thunderdome 2019 - the biggest indoor hardcore dance event

Guardian looks back and Thunderdome 2019, held last week in Utrecht, with 50,000 ravers at a convention centre making it the biggest indoor hardcore dance event ever staged. It all started in October 1992 with four relatively unknown DJs, organized by two plucky 20-year-old schoolfriends from a village outside Amsterdam, to become the world’s greatest living hardcore rave.
