My best to Ferdinand and Eva! It's a shame they have such poor material to work with (my concerto), but I'm confident they will make it sound far better than it deserves. Wish them success for me, Alex.
BTW, Ferdinand has served as a great inspiration for one of my students who is just a couple years younger. I had him watch the video of Ferdinand playing and it showed the young lad just what he could be doing ... if only we could get him to practice!
