according to Schott's site, will be performed in Tampere February 8. (Conductor Muhai Tang is mentioned, not the soloist, I see.)
Mihail Slobodjaniuk will be the soloist, a member of the orchestra.
Thanks, both of you, for the information. Fascinating.
I got to hear it last week at the Crane School of Music in upstate NY played by the student orchestra with a student who won their 2013 Crane Concerto Competition playing. I had never even heard of it before. It's very lyrical.
