Dream Theater is in the process of reissuing all their demo and live albums that used to be available through their YtseJam Records. Now the band has unveiled their entire performance of Iron Maiden's classic 1982 album The Number Of The Beast, recorded at La Mutualite in Paris, France in 2002. Much like the covers you'd find on the Change Of Seasons EP or a few of the other YtseJam Records live bootlegs, they're pretty straightforward and true to the originals. Though Dream Theater being Dream Theater, of course there's some variation here and there.
If you're looking for more YtseJam Records stuff, definitely check out the Falling Into Infinity demos here. The demos include songs cut from the final album like like "Raise the Knife," "Where are You Now," "Cover My Eyes," "Speak to Me," "The Way It Used to Be," and even "Metropolis Pt. 2" which later became the band's 1999 classic Metropolis Pt. 2: Scenes From A Memory.
