Peripatetic musical maven Phineas McBoof (who happens to be a monkey) has formed a new orchestra in this newest installment of the series written and composed by Cory Cullinan. Here, the McBoof saga continues in a wacky — and unexpectedly informative — musical adventure in two acts introducing listeners to the worlds of opera and the symphony, with jazz, hip-hop, Broadway and, specifically, Beethoven thrown into the mix.
