Listened to the three official bootlegs by Dream Theater that I just got.

This one is two discs, the first is the entire DSOTM album covered live. A stellar performance! The second disc is a collection of Floyd songs that DT did live in tour, its called "A Saucer Full of Floyd". The performance is mind boggling considering it is live. These guys are serious musicians.

I think these guys do a better live performance of this album than Metallica themselves, except for maybe Labrie's voice which isn't the best for this music IMO.
next up..

This is what Labrie voice is better at doing. This is right up their alley and another amazing performance. I imagine DT is something great to see live.
