Not quite the first ascent - first free ascent. The route was first done solo by Casarotto in 1979 with a mostly free version done in 1984 by Kearney and Knight. Has seen few repeats until the last couple of years though.
The billing claims it as the 'first free ascent' and then adds 'in ultra minimalist style', so may be this was the first truly free ascent in Alpine style, in one push??
