Céüse, France, is home to Biographie, Chris Sharma's legendary first ascent, which at the time was recognized as the world's first 5.15a route. Sharma returned in 2012 and left behind a project: Rastaman Vibration. No one has claimed the first ascent since then. In this video, watch Charles Albert and Seb Bouin working the line. Apparently it's difficult.
