You had better buy this before it disappears and becomes a collector's item (see his CD's of Bruckner symphonies with Munich, if you want an example).
The whole disc is mind-blowingly extraordinary, a wealth of great music, performed with depth, beauty and sensitivity. The only other thing I'll say is that, once you've heard Celibidache's Prelude to the Afternoon of a Faun, you will never be able to listen to anyone else's performance ever again. This is a performance that will leave you in a puddle of tears, if only you will allow yourself to love the glacial tempo. When I play this recording for my students in my music appreciation classes, 90% of them fall asleep; but, for the other 10%, it changes their lives.
