Their First, Pablo Honey, is generally viewed as their worst. it has quite a rough sound, very raw, but i like it, personally. But it isn't as good as their other albums. Notable song(s): Creep

their second and third albums, the bends and OK computer, are alike, but only relative to the rest of their work. I really like both of these, but I would prefer OK computer to The Bends

Then came a more electronic phase, with Kid A and Amnesiac, followed by Hail to the Thief, which was similar, but heading back towards guitars.

My favourite Album(s):
OK Computer (guitar melody based)
Hail to the thief (electronic Mainly)

Sorry to be so vague, but Radiohead are such a band that to take one album to represent them entirely wouldn't be doing justice to the band. I think of those two OK computer would be better for starting off, as it is generally their most acclaimed album, but others might have a different opinion.
