That's absolutely rediculous to say that nirvana songs are easy to play.
Ofcourse the rhythm guitar and chords are easy to play but I'd like to see
one person just one person play all of the notes for In Bloom, or Serve
The Servants, or Oh the Guilt, as it appears on record no one can, but he
could replicate them perfectly on stage cause kurt had a very crazy
phrasing technique. If you ever saw nirvana play live then you would have
seen the unbelievable amount of skill kurt had. In the middle of a solo
he would throw his guitar down and bounce it straight off the stage and
back into his hands while still playing. I'm sure you've even heard of
the many times he played guitar while standing on his head! Even Guitar
"masters" like Steve Vai and Eddie Van Halen have acknowledged the real
talent and skill that he had.
