I was in middle school when the White Album came out, it was probably the most feverently anticipated album of all time - with the possible exception of the Springsteen box set.
Although the White Album, overall, is great, I would vote against it for two glaring faults-the inclusion of Revolution 1 & 9. Revolution (the single version) was a huge hit at the time, and is a great song. Revolution #1, the album version of the song, is painfully tepid and slow. Revolution #9 is a total joke-its basically nonsense music that most people will only listen to once, and even then probably not all the way through.
With a CD you can easily program around these glaring faults, which is not as easily not on a LP. With two little changes (put the single version of Revolution in place of Revolution #1 and dang near anything in place of #9-even silence)-this would have been the best double album ever.
My nominations for best double album, in a major artist category, would be the Allman Brothers, Live at Fillmore East (best live album ever, and the peak of this excellent band) or Springsteen's "The River" (great blend of hits and back tracks, first showing of the true quality of work he was to do). My personal favorite, and probably not heard by too many people here, would be Todd Rundgren's Something/Anything?-Rundgren plays everything, which is usually a certain sign of diaster, but is an absolute pop masterpiece.
