|I remember I used to mistake with his Sinfonietta La Jolla, but once you listen to it it's unmistakable. Firstly because it's a sinfonietta concertante and the piano is as prominent as in his concertante even if it isn't exactly in the same way. And secondly because the work's mood somewhat collides with its title, you can feel the wartime atmosphere as much as in this same year's Fantasy and Toccata. I guess the giocoso part comes from all four movements being toccata or scherzo-like, quite is quite unusual, or maybe from the I occasionaly feel. There are very few slower parts to catch breath and so much sincopated frenzy can be somewhat distressing, but I think it suits what this music actually carries, and if you like the most dynamic Martinu this is definitely a treat.
