Funny thing Dream Theater did on they World Tourbulence was to play whole Master Of Puppets album. I don´t know why but they probably like Metallica and really like Master Of Puppets. And what´s funny about it is that it sound way better than the album. Not that album isn´t 100% corect, it´s just the sound. Dream Theater live sound is way better than the sound on Master Of Puppets album. Man, they must have they best sound in the world live.
