Following its compelling opening Masterworks Series concerts last month, the Knoxville Symphony Orchestra embraces an intriguing program for its October concerts this week that feature Edward Elgar’s Cello Concerto in E minor with guest soloist Zlatomir Fung, along with Igor Stravinsky’s delicious folk-fantasy ballet score, Petrushka. Maestro Aram Demirjian will be opening the concert with the eight-minute Floridian Symphony by Meilina Tsui—receiving its first performances in the state of Tennessee.
