Dream Theater's second filmed appearance in Japan since 1993 may very well be the best thing they ever put out, and for many good reasons. It showcases their more metallic side (Train of Thought and Six Degrees are the main focus), and illustrates that Portnoy's filmmaking skills have finally caught up with his drumming and lyrical skills. Don't worry, they play a couple classics as well. The band shows more power and chemistry here than any of their previous concerts - even their softer moments have bite. The only criticism I have would be James LaBrie's uneven vocal performance. But when the music around him is this good, why am I complaining?!?!
If you just want DT, playing live, with no added frills - just a standard, powerful, live show with an awesome setlist, plenty of jamming, and an awesome encore, this is the one to get. It's a really close competition between these live albums.
