Phineas McBoof, a rock star monkey and member of the touring Band of Misunderstood Geniuses, eventually finds the crowds too unwieldy, so he sneaks away. The other band members, including Backbone the Octopus, Bottomus the Hip Popotamus, Riley the Robot, Lenny Longtail, Sidney the Beak, the Ooh Gah Boo Gus monsters, Placido Flamingo, Luciano Frogerati, and Dr. Noize, go looking for him and find him conducting an orchestra. So the band members decide to join the orchestra as well. Phineas and the orchestra members have to overcome obstacles such as interfering parents and levitating instruments on their way to putting on their concert. This two-act musical comedy features Grammy-winning stage singers Isabel Leonard and Nathan Gunn, the City of Prague Philharmonic Orchestra, and the Colorado Children’s Chorale. Opera and show tunes dominate the musical styles. During the course of the story, the orchestra explores types of music from different eras: early (Gregorian chant), baroque (Bach), classical (Mozart), romantic (Chopin), and contemporary (jazz). They also play and discuss Beethoven’s 5th Symphony.
