The London Philharmonic Orchestra reports that they will perform several commissioned works the 2014-2015 season, including the world premier of a concert work by James Horner, "for four horns." On March 27, 2015, Horner's new concert work will be showcased between performances of Tchaikovsky's Fantasy Overture from Romeo and Juliet and Rimsky-Korsakov's Scheherazade. This proceeds another concert work we've also reported on: a double concerto for violin and cello, to premier in Liverpool this November.

This is very new news. We will report more as we learn further information.
