Playing and singing is not a big deal...Hendrix was a MASTER at playing and singing well(While high as a kite or tripping balls too).

If the REAL question is 'who got the ball rolling for the bigger genre' than kurt is the 'winner'.

But,if the question is 'who played guitar better and wrote better songs' then Hendrix is the 'winner'

While were debating these two icons,I should bring up that my hero,Chuck Schuldiner played better guitar,wrote better songs(sung and played) and got the ball rolling for death metal and its insane amount of sub-genres...

Chuck Shuldiner owns them both!
