The only Radiohead album I own is OK Computer, and I thought it was bland and mediocre. I'm going to give Kid A and In Rainbows a shot, so hopefully I'll be able to appreciate Radiohead as much as 90% of this forum does.
Nice review btw.

I would try Kid A and Amnesiac, I like Amnesiac more than In Rainbows, I actually like all their albums except Pablo Honey more than In Rainbows. The Bends and Hail to the Thief are really good too.

In Rainbows is by far the most accessible of their recent works, so I personally would say to give that a shot before the others. If you though OKC was bland, Amnesiac will likely do no better for you.

Holy crap. Kid A fecking pwned.
I'll try In Rainbows next, but seriously, that was surprisingly good.

What are your favorite songs on it? Mine are Everything In It's Right Place and Motion Picture Soundtrack

If you like Kid A definitely give Amnesiac a listen. It's the only one of their albums that sounds anything like Kid A and if I remember correctly it was culled from the same recording sessions.
