Thanks. Can you please tell me who produced this recording(label)? Amazon shows me one with Marriner and the ASMF, but none with the BPO.
The recording of the Clarinet Concerto that Robert Newman mentions is on "Mozart Wind Concertos" Berlin Philharmonic/ HVK : EMI Studio. You won't be disappointed with this CD, if it's still available.
As for Mozart symphonies, this is how I would rate the best recordings:
25 Klemperer
29 Karajan
31 Bohm
35 Klemperer
36 Karajan
38 Karajan
39 Karajan
40 Bohm
41 Bohm
HVK and Bohm recordings are all with the BPO, and of course Klemperer is always with the Philharmonia Orchestra. Of all conductors, my favourite is Klemperer. I also like Bohm (especially for his opera) but these symphonic recordings are second to none.
An alternative in all cases above is Sir Neville Marriner/Academy of St Martin in the Fields. They are excellent but I just find the above rather better. There is also a Szell/Cleveland Orchestra version of S 35 Haffner which is very good.
Mention was made of Mozart's Clarinet Quintet KV 581. Undoubtedly, the best I have of that is by the famous Juillard String Quartet (on the Maestro label, 3 CD set).
Mozart for ever!
