This set features the concertos for solo keyboard and orchestra actually composed by Mozart. Concertos Nos. 1–4 (K. 37, 39, 40 & 41) are orchestral and keyboard arrangements of sonata movements by other composers, arranged by the child Mozart for composition lessons and are not included. The unnumbered concertos for two and three pianos are also not included. Originally issued in separate volumes by the Dabringhaus & Grimm label, the concertos are performed by Christian Zacharias with the acclaimed Lausanne Chamber Orchestra.
