I've seen these guys ~4 times now. I just saw them at Club Nokia in Los Angeles, on October 12.
I adore the fact that they are keeping Pink Floyd's music alive, the attention to detail, etc.
I think they take the fan's viewpoint - if you were to hear Floyd live, how would you want it? The music is note for note solid. No undue improv except perhaps for where there is natural improv, e.g., ending a song that normally segues to another song, the Kangaroo in place of the pig, etc. Some things you just have to hear in sequence, like side 1 of Dark Side.
At the intermission, the main downside I heard is that the lead vocal just doesn't make the cut. I have to agree. Alex is a good singer, just not the right singer for *this* band.
If you are going to play keyboard for Great Gig in the Sky, you have to play it like Richard Wright played it. If you play Wish You Were Here, the opening has to sound exactly right. So in a similar vein, if you are going to sing a song with David Gilmour's signature sound, you have to sound close enough to Gilmour. Alex is not close enough. There are some songs where David and Steve have similar vocal duties - they *do* make the cut.
A comment on Great Gig in the Sky. This is one of those songs that if you have the guts to play it, it has to be spot on. I adored Bianca's interpretation - when I last saw it, my concert mate turned to me at the end and said, "Oh my God, she nailed it!". When I saw Lorelei on YouTube clips, she only sang a portion of it, and I thought that might be the plan. So, it was heartwarming, and a relief, to hear Lorelei belt out the entire piece - and Nail It. Whoever managed to get her to join the tour, I toast you all.
Favorite moment: Mike's enthusiasm and gyrations between his sax duties.
I personally want to thank Steve, Colin, Jason, Paul, Mike, and David for the Musicianship, the craftsmanship, and respect for the body of work you are keeping alive. Thanks to Emily, Lara, and Lorelei for the perfect backing vocals. Huge thanks to Lorelei for the gift she gave me with Great Gig in the Sky.
A note to management: Standing GA tickets guys, seriously? Do you know your demographic? Bring it back to the Greek or the Nokia Theater, where there are proper seats. This is a spectacle/experience show.
On the 3D stuff: Glad you tried the experiment but I would not repeat it. By definition, the 3D glasses are cheapies, easily smudged, etc. I would rather enjoy the visuals on Mr. Screen in their glorious 2D form and not have the cheapie glasses color the way the band looks.
PS: I'm the guy who has the Dark Side prism logo painted on his van's hood.
