This question has just occurred to me.
Kurt Cobain was a trailblazer. He defined the music of his generation - in case you didn't notice!This questions is really quite silly. Kurt Cobain isn't even a great musicians by rock standards, he wrote some popular music but that was it.
I think a lot more highly about Dave Grohl anyway
Meh...If you say so.Art is not just about complexity and virtuosity. That said Cobain was a great artist, and obviously so was Mozart, but the comparison is silly as the two were absolutely nothing alike in their approaches to art. Its like comparing Michelangelo to Clementine Hunter.
