Do you need a jolt of Broadway musical energy, something that crackles and pops while simultaneously gliding on joyous melody? Do you pine for a musical score that summons the old-style musical, evoking nostalgia for song and dance? Do you long for a show that is both fresh and familiar, the antithesis of the “sturm und drang” of most contemporary musicals? If so, then do I have a treat to recommend to you. The Original Cast Recording of the new Broadway musical Bandstand is guaranteed to deliver all of what I have suggested and more, making the case for a healthy run for this “;ittle musical that could.”
