Many years ago, the famous Hoffnung Festival classical music comedy series offered a "Concerto Popolare," a piano concerto movement made up entirely of recognizable themes from famous piano concertos. Rota's Piano Concertos, two of which receive their premiere recordings here, are less amusing because the themes aren't familiar, but the styles certainly are: Rachmaninov here, Grieg there, a large dash of Ravel, and so on. The performances sound entirely competent, as though the performers actually thought this was important music. But it's just the same kind of stuff Rota churned out for his famous movie scores, only less useful. --Leslie Gerber
