I've been thinking that our British friends might have us beat in this argument.
Now I grew up in the 70's and 80's so this isn't meant to be a complete list(I'm no expert),but just what I can come up with...what I'm familiar with.
On our side of the Atlantic we have many old time blues artists...blues gutarists that probably many people aren't specifically familiar with(me include),but have produced alotta great stuff....I guess these guys are the real pioneers of rock & roll.I believe these first guys are unique to the states.
We also have the whole southern rock deal....bands like Skynyrd(I love this stuff)which is pretty much exclusive to the states....maybe even blusey...
We have many guitar heros....I guess they have their share too...
Don't know how they're fit for Metal(Metallica)type bands?
Anyhow,I'll put down a lil bit of a list some....biggie's,the mosnsters IMO....feel free to add to it.
Stevie Ray Vaughan
Funny,now that I'm tryin to put a list together I'm blanking out...
We should win, after all WE invented rock and roll!
Aren't they Australian?
I don't think that any of the great British bands you mentioned could've done what they did for music, or become as famous for that matter, if it weren't for American audiences and support.
