This 11-disc boxed set presents the run of Dream Theater albums from Images and Words through to A Dramatic Turn of Events in no-fuss cardboard sleeves, presented in a clamshell box. The sleeves themselves are not as cheap as some of the "original album classics"-like sets that are out there, and because Dream Theater were very much a band of the CD era it's not like you are losing out on masses and masses of details from the artwork from this approach, so the overall presentation manages to be cost-effective without being cheap.
As for the contents - well, fans of the band might quibble about missing out When Dream and Day Unite, or query the lack of A Change of Seasons (strictly speaking an EP, but a fairly important release in many fans' estimation) or any live albums (but their best ones from this era were triple-CD releases), but these would all be quibbles. The fact is, if you've been after a physical Dream Theater collection want a nice, compact, cost-effective way to start it off, this one purchase gets you the majority of their studio albums (including many of their absolute best) in one fell swoop.
