Many reviewers have already made the case for purchasing the album, so I want to try to make the case, for those who can afford it, for buying the mono CD.I think most of the stereo mixes are terrible, with extreme left-right separation. Perhaps they were made to sound good when played on older mono equipment, but they render most of the songs lifeless. "Everything That Touches You" and "Birthday Morning" particularly benefit from their mono mixes. The album is probably best listened to through speakers, but it still sounds good on headphones. The liner notes mention that some of the band members were not satisfied with the final mixes. I wonder if they only heard the stereo; the notes also mention that the mono LPs were intended for (presumably, AM) radio, not general release.There are some downsides to this disc. For one, unlike the re-releases of the first three albums, there are no bonus tracks. Perhaps there were no original single mixes. It would have been nice to include the "Six Man Band" single, which was recorded shortly after the release of the album, not during these sessions. Also, tape hiss is audible in the quietest passages, but I didn't find it distracting.
