OZ: A World Premiere Musical This captivating COVID-delayed new chamber musical by freeFall’s talented stalwarts, Michael Raabe (music & lyrics) and Eric Davis (book & lyrics) is an unmitigated joy as it explores Baum’s conflicted impulses. Davis’s whip smart book moves briskly to connect the melodious 18-song score, often using fan letters accompanying projected portraits of porcelain doll-faced children who alternately gush, cajole, and finally, beg Baum not to abandon his “Oz” series.
