Nice Review, Ian!
If you enjoy the Rite / Firebird and want to go "In Depth", there are excellent (and rather amusing!) Live Performances of both Ballets with Gergiev/Mariinsky on Blu-Ray. The sound quality is a bit raw on my Big System, but very acceptable on Headphones with a Valve Amplifier. They are Perennial Favourites around Halloween, at Retirement Homes where I entertain with my Big System year round.
There is also an excellent Rite Documentary by Michael Tilson-Thomas on DVD, but the actual Concert Performance was, in my opinion, spoiled by Camera Work which tried to Jazz-Up the Visuals. MTT's other Documentaries have become better and better, especially the ones on Shosta 5 and Mahler...
p.s. Scotland is becoming a Force in Reviewing - I. Giles (Ian) and I have corresponded, and he has the advantage of being a Photographer and former Classical Trumpet Player. Last time I checked, he was ranked somewhere in the 50s too.
