Just some subjective opinion here, keep in mind that I'm a huge Pink Floyd fanboy.
Just got this concert Blu-ray around Christmas time, haven't had a chance to fully enjoy it until today. Overall there are some excellent pieces of music here, with a terrific Dolby TrueHD 5.1 and LPCM 2.0 mixes.
The concert contains an albums worth of new material from the Pink Floyd guitar master, as well as some old favorites (and not so favorites) recorded at Albert Hall .
By far my favorite performance is a rare version of Echoes from the 1971 album "Meddle", complete with oft-called "seagull sequence", albiet slightly shortened. Gilmour's guitar and Richard Wright's Organ/Synth take the leads in the mix, and maintain terrific seperation. Other notable Floyd pieces include Time, Speak to Me/Breathe, Shine On You Crazy Diamond, Fat Old Sun, Wish You Were Here, Comfortably Numb, and even a VERY rare performance of Wots...uh the Deal? For a slightly obessed Floyd fan like me it was great to see DG playing guitar on tracks like Echoes and Shine On again, he is truly a master of phrasing and tone.
If there's a negative, some of Gilmour's new music is a bit slow and difficult to swallow for me. But other parts of it shows the blues style that Gilmour brought to Floyd, and transformed the band's sound after Syd Barrett fell from grace.
The Dolby TrueHD 5.1 mix is phenomenal. I played it through my PS3/Onkyo 705 combination. The PS3 reported a 4.0-4.6mbs rate (2-3mb for the 2 ch PCM mix) througout the performance. IMO channel seperation and ambiance were amoung the best I've heard yet from a concert release. I did notice that surround channel use was mostly for crowd/ambiance/background information, which is fine by me, since this is usually the case when you are at a concert.
This is definate must have for any Floyd fan, and even worth checking out for those of you only mildly interested. At only ~$25, it's a great Blu-ray bargain, and possible reference material for those of you looking to "wow" your friends/family.
