In 2007, Phyllis released UnCaged Toy Piano, her debut solo toy piano album on the Concert Artists Guild label.  The album includes her recording of the  seminal work “Suite for Toy Piano” by John Cage, as well as a handful of works that use the toy piano with other instruments. The album also features music written by Phyllis, The Memoirist parts 1 and 3, which is from the miniature theater piece she created with her husband, Rob Dietz.
