After a very successful 2026 edition, Heavy Week-end is returning to Nancy Open Air to give heavy metal and hard rock fans a fourth edition every bit as spectacular and thrilling as the last. Join us on Friday, June 4, Saturday, June 5 and Sunday, June 6, 2027, in the Grand Est region, for three more explosive days. On the bill? Germany’s Helloween, America’s Falling In Reverse—and, of course, Marilyn Manson!
