Looks pretty good!
I used to own Boulez's old recording of M10 Adagio (forgot the name of the orch.) which I liked a lot.
I think he should do more Bruckner though - his B8th is a model of clarity, balance, and a logical argument, all of which work extremely well for Bruckner's music.
Didn't he record B9th sometime but decided not to release it for some reason?
