Master Vengerov appears to be a very tender conductor and certainly knows his score (what each instrument should be playing, and when to "bring out" certain instruments...) alas, he seems a bit hard to follow here. I often don't quite know what the metre is... but then again - I'm not reading from this particular score and haven't played this piece.
3 years after finishing this symphony Mendelssohn even began working on a fascinating 6th symphony in C-Major - hardly known by anyone --> see ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6SktTBKjV10.htmlsi=0oYXuoBEIIicnTHF !
