Be Here Now is always slated, but it's the only Oasis album I ever go back to, principally because it encapsulates the over-confidence of the period so well.
Agree with whoever mentioned New Adventures In Hi-Fi, my favourite REM record.
The RHCP album with Dave Navarro, One Hot Minute is also underrated. I find it interesting to listen to how the addition of Navarro changed the whole dynamic of the band.
The Strokes second album, Room On Fire was unfairly slated IMO, some really good stuff going on there, and far superior to their new record.
And what's wrong with that?
