Alexander Huber has soloed a 22 meter long 8b+ route at his favorite crag, Schleier Wasserfall in Austria.

Huber climbed Kommunist early on the morning of April 20, 2004. He had hoped to be completely alone for the ascent, but after he warmed up and did some bouldering a hiker arrived. Huber drafted the hiker to hold his videocamera, not telling the unwitting cameraman what he was about to film.
