I agree with most posts, won't repeat albums that have been mentioned.
Elegantly Wasted - INXS (their final Hutchence release is quite solid from start to finish).
The King of Limbs - Radiohead (seems to be hated by a lot, but I think it is quite good).
Pink Floyd - Meddle (a great album that gets overlooked on the whole because of its epic closer)
David Bowie - Earthling (perhaps ahead of its time, I like the industrial influence)
R.E.M. - New Adventures in Hi-Fi (I think REM fans tend to like it, but I don't think it gets the recognition it deserves).
Pearl Jam - Binaural (Perhaps too mellow for most Pearl Jam fans, it is an excellent album that I've grown to love).
