My take on Radiohead - In Rainbows:
It's a very good album that I enjoyed on first listen. It didn't blow me away, which isn't necessarily a bad thing as some of those albums tend to get "dull" in the long run. Instead this album is a nice balance of laid back rock and fun/dancey pop-rock. I'm once again very impressed by how Thom Yorke uses his voice more as an instrument (people might or might not like this, but he probably sounds the most "normal" on this album, as in not over-produced with digital effects).
The layering (sounds take on their own space, are softer/louder/more textured/detailed than others), and mixing in this album is just as good as past Radiohead albums and sounded sublime on my L3000s though the limitations of the CBR mp3s reared its ugly head . And the album could have done with less gain.
My favorite tracks on the album are 15 Step (what a way to start an album! Though it might have been too strong an opener as it gets progressively mellower from there on) and Weird Fishes/Arpeggi.
Overall impressed and I like it a lot more than Thom Yorke's solo album, which I was pretty disappointed with. And I'm happy I preordered the discbox set, hopefully the outtakes are just as good
