Thirty-three people have been injured after lightning struck a German music festival where Motorhead, Foo Fighters and Marilyn Manson are playing this weekend.

The first eight of those impacted were part of production teams at Rock Am Ring, held in the town of Mendig. That strike occurred around 1 a.m. Saturday morning local time, roughly an hour after Manson left the stage. Rock Am Ring was halted, and fans were moved into lightning-proof tents. But a second bolt, this time around 4 a.m., was even more damaging, injuring 25 people at one of the campsites.

As the news of how many people were involved in the incident spread, Rock Am Ring performers like Dan Smith of Bastille began tweeting their best wishes:

None suffered direct hits, though all of the injured were under medical observation. Organizers said Rock Am Ring will move forward as scheduled. Other featured bands include Slipknot and the Prodigy; they are playing before an estimated crowd of some 90,000 fans.

Rock Am Ring – said to translate as Rock at the Ring – arrives at a busy time for Motorhead, who will release Bad Magic on Aug. 28 to mark the band's 40th anniversary. Motorhead will also launch a new European tour later on this winter. Foo Fighters, meanwhile, return to the U.S. in July, with dates continuing into October. That includes a two-night stand in Boston, where they’ll play on July 18-19.
