I need some help placing the following Radiohead sound in songs such as...

..."Sail to the Moon", "Exit Music (For a Film)", and "Motion Picture Soundtrack".

I know it's not necessarily blues or jazz, but it's the closest genres I could think of. If any of you know these songs, could you help me out here? It's been bothering me what to describe it as.

Umm, try the official Radiohead thread. You're not gonna get much luck here.
According to BS statistics, 92% of teens have moved on to rap. If you're among the 8% who doesn't consider rap to be real music, donate your brains, as you clearly aren't using them.
