If you're not familiar, the 'Eisbach' -- German for "ice brook -- is a small man-made river slicing through Munich, Germany. There's a man-made wave that's been surfed since 1972. This edited by Saubere Filme does an incredible job documenting what it's like to shred the urban river in the blackness of the night. Watch "Slicing Time" below.
