Frankly, I didn't understand what all the hype was about. I picked up this album about the time it came out, a friend of mine recommended it to me. I've never listened to Radiohead before, but i am a fan of Pink Floyd and the Beatles, and i have no idea how someone could comment that Radiohead has the same style. Even with Roger Waters, Pink Floyd's sound was never so...slow. Even on their most mellow CD's (the wall for example) you still have tracks which speed things up, tracks like "another brick in the wall" or "run like hell" pick up the pace. EVERYTHING on OKC is slow and mellow. By having that slow a tempo, OKC just goes on and on... i think this would be okay if they interesting lyrics.
Actually, i think this album would be alot better if i could understand what Yorke was singing. It sounds like he mumbled the entire album in his sleep. Even the lyrics booklet was unreadable. When I first listened to it i thought, "no problem I'll just read the lyrics instead of listening to them" but when I opened the book, the lyrics were almost as incomprehensible as yorke's voice. Half of the lyrics look like they came out of an E. E. cummings poem! I didn't even know it was a concept album until i read the reviews.
Although some of the guitar work is interesting, and the sound effects are cool. Lyrical incomprehension(I don't mean understanding the words, I'm talking about trying to figure out what they said) brings this album way down. And its slow pace does little except to make Yorke's voice even more annoying. I don't even know how other people managed to understand the lyrics, perhaps they found them on the internet(which, according to you reviewers who think this is a lyrical work of art, is exaclty what the album was criticizing).
