Joseph Trapanese is a composer and music producer known for integrating his extensive classical training with his skill producing electronic music. He has crafted uniquely hybrid and inventive scores for a number of film and television projects, including Tron: Legacy (with Daft Punk), Oblivion (with M83), The Raid (with Mike Shinoda), Spiderhead, America the Beautiful, Prisoners of the Ghostland, Lady and the Tramp, Stuber, Arctic, Straight Outta Compton, The Divergent Series’ second and third installments Insurgent and Allegiant, The Witcher, Shadow and Bone, and interactive projects for Disney Animation, EA, Lucasfilm, and Ubisoft. He has also collaborated on songs for The Greatest Showman, Divergent, and Jason Bourne, and worked on albums and live events with musicians including Aloe Blacc, Amon Tobin, Dierks Bentley, Dr. Dre, The Glitch Mob, Haim, Halsey, Janelle Monae, Kelly Clarkson, Kendrick Lamar, M83, Moby, S. Carey, Sohn, and Zedd.

In 2022, he was commissioned by NASA to write the theme for the 2027 Mars Sample Return mission, and in 2021 he contributed production and arrangements (alongside Adam Blackstone) for the Super Bowl National Anthem. Trapanese's choral composition New Collective Consciousness, featured as the opening of Bjork's 2022 west coast concert tour, addresses the climate crisis through its intense harmonies and dissonances, striking choral textures, and unique text drawn from Greta Thunberg’s 2019 speech at the United Nations.

Trapanese has conducted the Hollywood Bowl Orchestra, Estonian National Symphony Orchestra, AUKSO Poland, and numerous festival and studio orchestras.
