Tom Vaccaro and Bret Churchill in A New BrainBeautiful vocalizations, rich harmonies, nuanced performances, and a fun, interesting set aside, what I enjoyed most about Saturday's performance of the District Theatre's A New Brain was that the musical felt both familiar and original; it's a fresh take on musical theatre, yet doesn't suggest any unnecessary effort made to reinvent the wheel. With its songs by William Finn and book by Finn and James Lapine, the piece manages to be odd, joyful, irreverent, and silly all at once, but also delivers an overarching sense of hope without being pandering or sugary.
