The correct titles of the works on this album are as follows:
Památnik Lidicim (Memorial to Lidice) for Orchestra, H. 296 (1943 New York)
Concertino for Piano Trio and String Orchestra, H. 232 (1933 Paris)
Rhapsody Concerto, for viola and orchestra, H. 337 (1952 New York)
Concerto for Piano Trio and String Orchestra, H. 231 (1933 Paris)
Notice that the final work is titled "Concerto" rather than "Concertino."
The Concerto was commissioned by the Hungarian Trio in 1933. Martinu completed the work and somehow managed to lose the manuscript. With time running out before the scheduled premier, Martinu wrote a substitute work in only eleven days, which he called "concertino." The Concerto and Concertino are in the same key and share the same four movement structure, differing slightly in duration. Although Martinu mentioned a Concerto for Piano Trio in his writings, most scholars assumed he was referring to the Concertino. After the composers death, the lost manuscript for the Concerto was discovered and finally premiered thirty years late.
If you like early twentieth century music by composers like Prokofiev, Stravinski, and Copeland, you should really explore the works of Martinu. This album is a perfect place to start since it not only shows off the composer's skill at writing for orchestra, but also touches on his great talent for writing chamber music.
