Sergei Prokofiev's Cello Concertino in G minor, Op.
Prokofiev had been impressed by Mstislav Rostropovich, after working with him for his Symphony-Concerto, so he undertook to write a number of other cello pieces for him.
The Cello Concertino was such a piece, intended to be of a light nature.
Prokofiev's death in 1953 left the work unfinished, the finale in particular.
However, the composer had indicated to Rostropovich what his intentions were, so he undertook to complete it.
