Depends on the music style...

Obviously Elvis, he basically introduced rock and roll. Led Zeppelin and The Beatles carried that on.

Pink Floyd were impactful because of their great lyrics. Black Sabbath introduced a heavier type of rock.

Metalllica and Megadeth introduced pure heavy metal music and dominated that industry. Then System of a Down, Disturbed and Slipknot (even though I hate Slipknot) introduced a new trend in Nu Metal.

And quite a few other bands were very impactful.

Where's my Bowie?

WTF?:( Nirvana essentially killed hair metal. Simple lyrics maybe, but an entire generation of kids and young adults took notice. Nirvana was to Rock n Roll in the 1990s what Led Zepplin was to Rock N Roll in the late 60s early 70s. It was a revolution. Kurt Cobain had heart and that was something that the hair bands didn't/never had.....this is of course my opinion.

I remember Nirvana before they were big (I live in the Seattle area) and I knew they were going to go far because they didn't try to copy any other bands. Influenced by other bands maybe, but never copied.

I actually admit that I do like Bowie and Elvis Costello....seriously.

I'm not going to argue with you on this. My posts earlier on in the thread already cover pretty much my entire feelings on the matter.

And thanks for making me re-read this thread, I'd almost forgotten why I put boo boo on ignore.

Defintely KURT COBAIN

Kurt Cobain isn't a band.

Van Halen and Queen!

I would have to say the most impact to create a rock like sound would be the Beatles. And I think that metal was created through the music of Led Zepplin.
