"I'm a movie enthusiast, and really involved in orchestra, so what better way to combine my two loves than to become a film composer! A lot of my influences come from Shostakovich, John Williams, including some mainstream artists like Beyonce and the band Terror Jr. I also like writing songs and creating pop instrumentals for vocalists. I credit Disney for my passion of wanting to become a film composer, because I want to provide magic through music to a younger generation, just like Disney gave magic to my imagination." -Cassidy R.
