In 1987, Ms. Mousios began formal studies in film and documentary scoring with Academy Award Winner, Joe Renzetti. Mr. Renzetti was so impressed with her talent that he asked her to assist with some of his film projects.

Frederick C. Lyman, Jr., a former music and jazz critic for The Yale News, described Ms. Mousios as “one of the most important musical thinkers of her generation.” 

In another critique of some of Ms. Mousios' later work, Mr. Lyman wrote, "Her music can be likened to no other with the possible exception of the Renaissance composer, Carlo Gesualdo, who has baffled scholars for centuries."
