The Boston Modern Orchestra Project (BMOP), the nation’s premier orchestra dedicated exclusively to commissioning, performing, and recording new orchestral music, begins its 24th season with a nod to the Jazz Age of the 1920s. The program’s first half spotlights the preternatural theremin (invented in the 1920s) with the instrument’s first concerto, written by Joseph Schillinger, juxtaposed with the world premiere of Dalit Warshaw’s Sirens: A Concerto for Theremin and Orchestra, both performed by world renowned thereminist Carolina Eyck. The concert continues with three works representing the Roaring Twenties and its fascination with American pop culture: John Alden Carpenter’s Krazy Kat and Skyscrapers, and Kurt Weill’s Little Threepenny Music.
