George Gershwin's ever popular Rhapsody in Blue was first performed in February 1924. To mark the centenary of that celebrated event, pianist Jeffrey Biegel commissioned composer Peter Boyer to write a work for piano and orchestra that would be a 21st-century partner to Gershwin's original. Raymond Bisha talks to both composer and soloist about the gestation of this celebratory new work that captures a similar propulsive energy, while interweaving allusions to blues influences and lyrical evocations of American vistas.
