Johann Christian Bach's' Concerto in C minor has become one of the most popular viola repertory pieces. The piece is however not by J.C. Bach at all, but rather a well-intentioned fabrication of the Casedesus brothers Henri and Marius. Henri Casadesus was an outstanding violist and presented this concerto in 1916 as a new discovery by J.C. Bach. It was subsequently revealed to be an invention of Casadesus himself, 'inspired' by J.C. Bach sources. This Edition Peters publication contains a piano reduction and offers the possibility of performance by viola, cello or violin, containing separate parts for these instruments.

Attributed to Johann Christian Bach by Henris Casadesus, who is widely believed to have composed the piece, this Concerto in C minor is presented with a piano reduction as well as a recorded orchestral accompaniment on CD.
