I was happy with Julian's performance until the very end of the last movement which becomes intimate and contemplative and includes four upward clarinet arpeggios starting on a low D. This use of the third inversion is very striking and looks forward towards Beethoven. It is very meaningful, as the use of a prominent sub dominant note in Mozart often is. I was disappointed and outraged that the clarinetist altered the D that starts the arpeggio, and started it down on a low B instead. This does not bring out the intimacy of Mozart's message of "but" or "I told you so".
