Rock am Ring festival organisers urged more than 90,000 festival goers to seek shelter in cars and tents as thunderstorms rolled through and threatened the event on Saturday.
Reuters said 71 people were injured, however the festival Facebook page said more than 80 people were injured by lightning strikes.
The sell-out festival, now in its 31st year, took place at the airport in Mendig, near the Nuerburgring motor racing track.
