Hello, when this becomes available will you need an orchestra for performances and rehearsals? Or will there be tracks?

Hi! The show is now available and currently does not have Performance Accompaniment Recording tracks available. To see a full breakdown of the orchestrations, go to the show's page and click the "Materials and Orchestration" button beneath the Cast Recording: https://www.mtishows.com/dr-seuss-how-the-grinch-stole-christmas
