The connection between the two works on this disc seems a little tenuous (Illinois seems to be the only obvious common thread), but at least the coupling provides some stylistic variety. Rudolph Ganz (1877-1972) was a Swiss-American composer, pedagogue, conductor and pianist, and may be better remembered for his other occupations than for his work as composer. His piano concerto was written in 1940 and is for the most part conservative and cosmopolitan but does include some slightly jazzy and dissonant elements. It is not a very memorable work, however, though undoubtedly skillfully written.
John La Montaine (b.1920) seems to be something of a stylistic polymath, having composed works in strict serial style as well as unabashedly romantic music and even folk-pop (apparently). The fourth piano concerto certainly draws on diverse influences as well. It is unashamedly tuneful and immediately accessible, mixing pop influences with stylistic traits that seem close to the music of Roy Harris. It is certainly attractive enough, and manages to sustain the listener's interest, but without offering anything really substantial or particularly memorable. The performances of both works are good and they are well recorded, however. To sum up, this is a worthwhile disc (and Cedille should have credit for exploring the repertoire), but hardly an essential release - both works are modestly attractive (perhaps in particular the La Montaine), but hardly more than that.
