All right, the gloves are off.
No one cares about The Jam here. I liked them fine but they were derivative -- the early progenitors of Green Day. Not that they sound like Green Day -- I mean that as with Green Day, even their evolution away from their roots was derivative of what other bands had done (until Weller did Style Council, which nearly caused me to strangle my college roommate when he dared to play it once).
10cc is an even bigger nobody here too; had one hit single I liked when I was a kid. I believe I've made my feelings on Radiohead clear many times -- hookless, arid, fake-depressive Pink Floyd rip-off merchants. I've never understood the appeal of Jethro Tull. I think Mark Knopfler is an overrated, overwrought, arrogant gaybaiter -- I cannot stand that guy, even if his music can be okay in small doses. Stone Roses did one record I absolutely loved and then disappeared.
Everyone else, fair enough, and as noted the top four in the pantheon (Beatles, Stones, Led Zep, Who) and arguably top five if you include Pink Floyd are British. The U.S. cannot compete. Not even close.
But all punk owes a debt to the MC5, the New York Dolls and The Ramones, not to mention the Velvet Underground (though Nico was German), great as The Pistols and The Clash are/were.
And when we get to "solo" artists, I think we'll find the US has just as many if not more in the pantheon than the UK, including a number I mentioned before.
And much as we're talking about rock, let's not fail to point out that the UK has IMO failed to produce a single hip-hop artist within ass-sniffing distance of any of the US top 25, maybe even 50, and like it or not, that matters in this day and age to the youngsters (since I think everyone on this thread is as old and white as me).
But at least we agree on the Beach Boys and Steely Dan, both of whom I like more than Springsteen, even though I think Springsteen is probably our greatest true rocker objectively.
