BTFW sounds great and the visuals are stunning as well. The keyboards and drums are louder than usual (for DT, that is), which really suited me, since those are what I care about the most. MM's kick drum is HUGE! I used to watch the shit out of Live at Budokan when I first got it, but I had even more fun with this one. My biggest gripe is that the rhythm guitar is muddy (I miss JP's Budokan/ToT tone) and the overall sound sometimes has too much reverb (which, on the flip side, contributes to a live feel).
For me, BTFW was a breath of fresh air after the disappointment which was LALP, with its weak drums, buried keys and aesthetically unpleasing visuals.
