No guitarist will listen to Nirvana for their guitars
only for their music.

My god, Curt was the singer, songwriter, and guitarist for Nirvana. He played and sang at the same time. What do you exept him to do?

If he wanted to be a great guitarist with really hard songs and difficult melodies, he could of done that probually.
Though he just stuck with simple chords to produce simple, but good music
