In these pieces there is very contrasted playing. Much of it is very good but the Strauss does not live up to the CD recordings the Karajan made. This is not his fault but some decidedly dubious intonation from Leon Spierer in the solo violin part.
The Mozart is, as you would expect, not of the "authentic" school of thought. The Menuett & Trio are played very slowly indeed. The rest of the performance is much more enjoyable with great care and delicacy exhibited by all.
The Strauss is of course played and conducted very well (apart from the above criticism) and has a shade more spontaneity than the studio recordings. It has some revealing camera work that allows one to hear previously unrecognised details in the score. Interestingly, Karajan is not the eyes-closed-demi-god that is so often portrayed but casts a beady eye over the proceedings.
All in all, I enjoyed it a great deal and would recommend it strongly to Karajan, Strauss or BPO admirers but it isn't the polished perfection that is usually delivered.
