Saw it in Detroit in October 2010 (with a 20 year younger gorgeous female friend to boot ) and was so impressed I just saw it again earlier this month. As a diehard Gilmour fan, I really thought I'd be highly critical of the guitar work, but I had to (only slightly grudgingly ) admit that the Dave Kilminster is a great, great player who nailed Gilmour's parts at every turn and added his own flourishes where they fit. His tone was buttery smooth, big and warm (unlike G.E. Smith's, which was like an icepick to the brain - brutal! Good enough playing, but brutal shrill tone). The show overall blew me away. Faithful to the original where appropriate, but mixed with great new animations and graphics that really make the timeless nature of the themes come through. I'd highly recommend it to anyone looking for something more than just your average "rock show".
I've been a huge Pink Floyd fan since college. I have most of their releases on vinyl, all on CD, and a ton of great unofficial studio and live stuff from all eras of the band (and find equal worth in all -the Syd, Waters, and Gilmour eras all feature music that crushes what most other groups were putting out at the time). As for guitar, I practically learned to play by learning Gilmour's parts by ear (he and Edward Van Halen are far and away my two biggest influences).
So in short...yes, I'm a "Floyd" fan.
