This is indeed the exact same bassline as in The National Anthem, but this album came out in 2003 and Kid A is from 2000. So as far as i know it's EST that was inspired by Radiohead and not the other way around.
this one is a historic jazz-song yet, modern, open to all kind of emotions in music! not this boring first- class-jazz, oh we are so special..., a chance to get out of the grave. Is there nobody: take this road, drive forward...!? sad about this.
