Liam Diethrich is a composer and violinist from the Chicago area. Diethrich began composing music in middle school, and at age thirteen, two of his compositions–a piano quintet and a piece for full symphony orchestra–earned live performances. Throughout his high school years, Diethrich’s works increasingly received national and international recognition, winning competitions including ASCAP, the Maurice Ravel International Composition Competition, the National Association for Music Education, and the Music Teachers National Association. In 2021 he received first prize at The American Prize competition in the instrumental chamber music category, and in the same year he was winner of the Juilliard Orchestra Competition. Diethrich’s compositions have been performed and recorded by professional ensembles including the Grammy award-winning Quintet Attacca, Amani Winds, the Juilliard Orchestra, the RTVE Symphony Orchestra (Spanish Radio and Television Symphony Orchestra), the Kankakee Symphony Orchestra, and the Urbana Pops Orchestra. Diethrich has studied at the Curtis Institute of Music Young Artist Program, the Atlantic Music Festival, the ICEBERG Institute, Interlochen Center for the Arts summer program, the GEMS Film Scoring program, and NYU film/media scoring workshops. He recently earned his master’s degree in Screen Scoring from USC, where he studied with Lawrence Shragge and Michael McCuistion.
