Query: A refreshingly new R.E.M. on its way 'Up'

This is possibly R.E.M.'s strongest album, and certainly makes up for the dissapointments of both Monster and NAinHF. An unusually somber album for this band, this reminds me of OK Computer by Radiohead, with many depressing undertones. It clearly is a different R.E.M. without Bill Berry, but their new sound is incredible, especially on songs like Lotus, You're in the Air, Walk Unafraid, Daysleeper, Diminished, and Falls to Climb. Michael Stipe's voice is as strong and powerful as ever. R.E.M. is a must buy for any fan, but except a new sound.
