The first thing to know about Out of the Box Theatrics’ Beau the Musical is that it’s mostly not about Beau. He’s an important supporting character in the show by Douglas Lyons (book, music and lyrics) and Ethan D. Pakchar (music), but Ace Baker (Matt Rodin) is very much the star. He narrates, plays the guitar, and sings practically every song. The next thing to know about Beau is, you have to stick with it. At first it feels pat, clichéd, and straight off the gay-pride-musical assembly line. Then, finally, Lyons’s characters acquire some individuality and become more interesting.
