The Chilli Peppers and the Foo Fighters for me. Well, modern ones. I'd mention classic rock but there's too many :band:

Well the way you posed the question makes it hard to answer so I'll divid eit up by genre.

Old school rock: Led Zepplin
New School rock: Edguy or Fireball Ministry
Hardcore: Either Zao or xDISCIPLEx A.D. both are legends
Emo: Taking Back Sunday most original emo band around
Metal: In Flames or Dark Tranquility

definetly not original dude.

originality in emo is hard to find nowadays. for some originalish emo bands that are still around check out books lie and van johnson. those bands are amazing.

I should of said most original of ones I've heard. I don't listen to much emo music....but I'll check them out.

go to hxcmp3.com

and listen to the cmhwak radio station.

everyband on there is good.

heroin to the one am radio to kodan armada

hell, if you listen to it long enough my band even pops up on their once or twice.

Pretty much every band that makes music these days is ripping off Led Zeppelin at some point and in some way. They were incredible.

That was a good choice. Haha, Boston is another good older band. Guns N' Roses. There's bunches.

Everyone loves Fleetwood Mac as well, they made some fine tunes in their time. Last album was woeful though.

these are just my favs not what most people would consider the best band:
Green Day
The Offspring

Iron Maiden are the greatest band nothing can beat them
