A wonderful performance. I've listened to this many times now and appreciate the joy your bring to me, as I particularly love the mandolin/domra instruments.
Alexey - I would love to hear this Sonata with the instruments tuned to 432 HZ for comparison. I suspect the phrases with those droning notes on the Domra would be enhanced with the slightly lower tuning? This is strictly from the point of view of tuning using Verdi's A, and the harmonics as compared to 440 Hz. I listened to Alon Sariel playing Bach Chaconne in 432 Hz and found it to be quite different - not as bright - compared to 440 versions which is a plus to my ears for many of these compositions.
