Concerts and recordings combine skills as soloist and band leader, guest lecturer and teacher, Cantorial Soloist, Unity Music Director, and contemporary new age, folk, stage, pop, and spiritual composer/lyricist. In congregation, concert hall, classroom, and in ten published recordings, Joy melds a repertoire of thousands of compositions with musical history, uplifting stories, insightful memories and sing-along ... touching the mind and heart and truly bringing joy. In the words of Tarpon Springs Montessori Academy Director Gail Gilmore, her programs are an "opportunity to explore culture beyond the limit of four walls." As composer/lyricist as well as in collaboration, she has produced numerous songs and works for stage. Recordings include her repertoire of original songs, original music for meditation, traditional and contemporary Jewish music, and selections from the popular American Song Book.

With her husband Mark, she operates Tune-of-the-Century Music® and Katzen and Guthrie Associates, Inc., offering Broadcast and Studio Design and Integration and Remote and Studio Concert Recording Services for a roster of musicians and organizations of all genres.

In both 1997 and 2003, Joy was awarded  Arts Resource Fund Performance Arts Grants from the Pinellas County Arts Council for the creation of new recordings of original music.
