Just got off a plane with my chamber orchestra. It's midnight in Poland and I'm wide awake. Today, I play solos for the president at 18;30. Eighteen hours from now—right after two days without sleep.
Maybe if I'm lucky, I'll nap sometime today.
Reminds me of a night voyage across the North sea in winter on a ferryboat with no seats (that weren't awash with beer and beer-drinkers), followed by a long coach drive to play a concert in Germany. Turned out it had been advertised for the following week so nobody came. Good concert though.
good luck! which orchestra is that? what solo will you be playing? are you the concertmaster? wish you a good concert!
