John Alden Carpenter, like his more famous contemporary Charles Ives, that highly successful New England-based life insurance executive, pursued musical composition as a sidelight to his successful career in his Chicago family business. Carpenter is frequently referred to as a jazz-age composer, and it is true that he was one of the earliest academically trained musicians to include jazz and ragtime in his work, but his three ballets are more conservative. The gently seductive Birthday of the Infanta, in particular, sounds infused with an idiom known as orientalism, which combines elements of Middle Eastern music with various folk sources. Krazy Kat is also pleasingly eclectic, with less overt popular music influence than the subtitle, “A Jazz Pantomime,” suggests. It is the snappy Skyscrapers that best captures the excitement and urbanity of the 1920s, but all three works, in their impressively diverse ways, are excellent and unduly neglected American ballet scores. It all makes for a fitting tribute to BMOP on the occasion of their hundredth release since its founding by conductor Gil Rose over 25 years ago, a remarkable accomplishment and an invaluable contribution to the legacy of 20th century American music. As always with BMOP, production values and sound are terrific.
