Presidio, you state that Nirvana was one of the most important bands in Rock N' Roll history. Why?

[discostu]

Out of their ashes rose the Foo Fighters, a much better band. Not sure if that makes them important, but it definitely made Nirvana useful. They were one of the first bands from the Seattle grunge scene to get signed, though they were by no means innovators within that scene.

The most important band in RnR history will always be the Yardbirds.

All bands that represent a major change in the direction of the genre are highly important.
