From the Inscape website:
In January Inscape returns to the Grammy-nominated studios of Sono Luminus to record a new transcription of Igor Stravinsky's beloved ballet, "Petrushka." Written in 1911 for Sergei Diaghilev and the famed Ballets Russes, the original Stravinsky work calls for an orchestra of over 100 players. For this project, Inscape commissioned noted composer David Plylar to transcribe "Petrushka" for the seventeen principal musicians of the Inscape Chamber Orchestra.
The recording of this new reduction will be released in 2015.
