I was able to sit down last night and start watching the first part of the main concert, I didn't get through the whole thing, but I was able to watch up to the drum solo.
Here are a couple of thoughts, only having watched those first 6 or so songs....
1. JLB sounds very, very good here. Is he playing around with the melody lines and phrasing things differently here and there? Yep! But I for one, like when vocalists do that live, so it doesn't detract from his performance to me. Can't wait to listen to him sing the rest of the songs, he sounds that good!
2. The mix isn't great, but it isn't that bad either.... I was just listening on my MacBook with headphones in (so the audio setting was just stereo) and I generally enjoyed the mix. That being said I'm a guitar player so the fact that the guitar was certainly up front in the mix was cool with me most of the time. I will say that JR is a little low in the mix, but I could hear JM fine and MM sounded pretty good too! In just watching the first few songs, the instance that the slightly low keys mix hit me was during the Root of All Evil. I'm so used to hearing the Score version, that hearing the song played with this mix made the lower key volume more noticeable to me. Like I said though, the mix isn't bad for my ears, but if I was to nitpick, I'd turn JR up a bit and maybe MM's kick drums in a few sections as well.
3. MM is killing it!! Love this guy and I didn't even get to watch the drum solo yet, I stopped watching right before it. Can't wait to watch that, this guy is a crazy good drummer. Watching him play some of the ADTOE songs makes me appreciate his parts on that album so much more, which is what I was hoping would happen. Being able to more clearly here some of the work he is doing on those tracks, along with being able to visually see it, really brings the parts to life!
4. A few weird things. During one of JP's solos, I think it was LNF you can clearly see that it looks like they edited together footage from both nights of him playing and put them together. One camera angle shows him playing with his foot up on his stand and then they would switch to a different camera and he was magically standing with both legs on the ground playing the solo, etc, etc... Its a minor thing, but I noticed it on my first watch of the song. And the backing vocals thing with JP I'm still trying to figure out as well... Sometimes he is faking singing and its pre-recording JLB backing, and other times he is singing but they mixed it super, super low. Seems a little odd to me, sure JP isn't a great singer, but with a little pitch correction help, I'm sure they would have sounded pretty good. I mean you can easily hear his backing vocals on their last couple DVD releases... Kinda weird, but once again, I'm not letting small things detract from my enjoyment of what seems like a great concert DVD.
Overall, I'm really liking it, still need to finish watching it but I'm generally pleased so far, it looks and sounds great! The band is truely on fire!
