The biggest heavy metal music festival in the world, Wacken Open Air, in Wacken, Germany, is touting improvements to its infrastructure.
At the top of the list: is a beer pipeline which the festival says will pump beer straight to taps at its main stage.
The festival organizers say the more efficient beer delivery system will reduce lines, wait-times and traffic around the taps!
"Until this year, we always had to move dozens of barrels through the infield," reads a statement on the festival's website. "We had to bring in full barrels before and during the shows and afterwards we had to remove the empty ones. This caused a lot of avoidable traffic."
Wacken also added fiber optic cables, power supply and additional speakers as part of improvements prior to this year's festivities, July 31 - August 6.
