After multiple decades living in the US as a Canadian national, I become a US citizen in 2 weeks. It's made me a little retrospective. I found myself curious about the sound that "is" an American band. For me...I finally came up with X. John X Doe and eXene Cervenka singing about lost love, heartache, hope and triumph...they brought the perfect blend of well crafted turmoil into their music.
Anyway, just my take...Lou Reed, Patti Smith, Bob Dylan and Bruce Springsteen for their poetry.
See, all of the US's problems come from the South. The North should've thrown the Civil War and said the hell with them. Anyway, back to Radiohead. Got the album today, going to listen to it at work tomorrow.
