Progressive is a very beautiful style of music with multiple shifts in tempo, and arrangements (building on riffs etc). It's like multiple songs (like 4 or 5) in one kickass package. I doubt this a true "opus" (or masterpiece), as the length isn't that great. :P You want an opus? Dream Theater's Octavarium is a great way to start..
