Of course its subjective and of course its a fluff thread! Qwitcherbitchin!!! Jeez, go throw ice on someone else's parade!!
Now, for good old down and dirty rock and roll it has to be Led Zeppelin. They were awesome. I also love Nirvana and Guns and Roses. For blues it has to be Ben E. King. For wimmen who ROCK it has to be Melissa Etheridge, Stevi Nicks and Heart. For Wimmin in Blues hands down its Bonnie Raitt. Don't listen to much country but when I do its the Dixie Chicks.
Oh and I'll think of more later.
