Here everything is different from everything that other leaders have played! The maturity and power (especially in the slow movements !!) give these symphonies a special tone and mystical.
The tempos are slow, but contrary to what the chef makes in symphonies by Tchaikovsky which is for me a sense-against (Russian Music EMI cabinet and French) in Bruckner absolutely masterful.
We may not like the third, or the fact that the versions 8 and 9 selected to be those of Haas Nowak and not, we can not love 7 in which the slow work for me worse than elsewhere, but listen to the 4th (in 79minutes! Counter 60 usually), or 8 117 minutes.
The slow movement of the 6th, rarely successful for me here this major symphony.
More importantly, if you have not listen to convince you that it is the 4: in the second movement, which Celibidache done around 9'30 "is just crazy: it meant nothing more than the pure genius.
We may not like, but you can not not have this set!
