I love this album. 'The Glass Prison' is an amazing powerhouse and has yet to get old. 'Blind Faith' is beautiful - many goosebumps per listen. 'Misunderstood' seems experimental but it is very playful and heavy at the same time. 'The Great Debate' is, for me, one of the greatest songs ever written. Period. Go ahead, just listen to it. Even the last track, 'Disappear', I would argue, is a small masterpiece - packed full of little, subtle, sweet details of artsy musical genius.

The 2nd disc will go down in history for having the longest, yet still tasteful song (as the entire disc is considered to be one song).

Overall, an amazing double-disc album.

A largely ambitious album, that although not quite as concise as 'Metropolis II', still manages to keep the listener from skipping any tracks at all. Some songs I think do fail slightly with unnecessary repetition, but when such marvellous songs as 'The Glass Prison' and 'War inside my Head' are so memorable, it's easy to ignore that.

I probably should check out this album someday. I think it's the only one I haven't along with the debut.

Revisiting this comment to wipe it clean and say this instead: Definitely their best work, in my humble opinion. I do believe this is their pinnacle. You basically get 2 albums, each one feels like a full experience in itself. There's a lot of variety and experimentation present, each side has a different feel to it, yet as it all adds up it makes perfect sense and nothing feels out of place. This thing just vibes, some relatable lyrical content in the pt.2 in my case. What can I say, this record is absolutely marvelous and unique.

Perfect Progressive Metal experience. If I had to pick one Dream Theater album which contains almost everything that this band have ever done, it would be this album. Essential.

Yeah, it's definitely one of their greatest albums. Their most ambitious and experimental release.

Nothing they've done since has come close to this.

I said Metropolis II was their best one... I was wrong...

THIS ONE IS WAY BETTER!!!

Just listening The Glass Prison did blow my mind

And obviously the homonymous track is a POWERHOUSE OF ABSOLUTE QUALITY!

This is probably their last "classic" record. Things started to go down hill after this one.

Just because of "Goodnight Kiss" and a few other worthy songs, I'm not going to say that it's a great album. Sorry, it's not.

Long and Boring at the same time.... is even rated more than falling into infinity
