Readers' Poll: Your Favorite Prog Rock Albums of All Time

Dream Theater posted this poll on their website (again, a totally kosher move), but it resulted in a ridiculous amount of votes for Metropolis Pt. 2: Scenes from a Memory. If we had kept in all the Dream Theater albums, Images and Words would be number two, and Awake, Octavarium and Six Degrees of Inner Turbulence would also be listed here. Lumping them all into this top spot was the only way to handle the flood of Dream Theater votes; feel free to label it whatever you want in the comments section. Dream Theater are one of the few prog groups to start after the Seventies and gain a massive global following. Unlike the rest of the groups here, they are a progressive metal group. Like most great prog albums, Metropolis Pt. 2: Scenes from a Memory is a concept album. It's about a guy named Nicholas and his discovery that he lived a past life. The whole album is actually a sequel to a song from the group's 1992 disc Images and Words, which in and of itself is a wonderfully proggy move. Dream Theater continue to tour and record at a relentless pace, though beloved drummer Mike Portnoy left the band in 2010.
