After a very good vintage in 2024, the Heavy Weekend returns to Nancy Open Air, to offer heavy metal and hard rock fans a second edition as beautiful and enjoyable as the last. Join us on Friday June 6, Saturday June 7 and Sunday June 8, 2025 in the Grand Est region of France for three explosive days of action. In terms of programming, Heavy Weekend confirms the arrival of Slipknot as its first headliner!
