Lior Rosner is the composer of the original underscore for Michael, the Antoine Fuqua-directed Lionsgate biopic produced by Graham King, now playing in theaters worldwide. An award-winning composer, arranger, and producer, his work spans film, television, the concert stage, and electronic music.

His credits include work on X-Men: Days of Future Past, X-Men: Apocalypse, Valkyrie, Little Fockers, Cirque du Freak: The Vampire's Assistant, Fantastic Four, The Losers, Seconds Apart, The Geography Club, and Wedding Doll. His choral piece They'll Remember You, featured in Valkyrie, received a World Soundtrack Award nomination and has since entered the contemporary choral repertoire.

For television, Rosner's work includes Netflix's Q-Force and AJ and the Queen, NBC's Will & Grace, The Ellen DeGeneres Show, Battle Creek, Forever, Heroes and Villains: The Secret History of Comics, and The History of Comedy.

In the concert world, Rosner's Sony Classical release Sugar Plum on the Run, featuring the Royal Philharmonic Orchestra and Jeremy Irons, has become one of the most widely streamed classical releases of the decade. He is also the curator and arranger of An American Renaissance, a concert program created for Grammy-winning soprano Janai Brugger, featuring orchestral settings of Florence Price and Billy Strayhorn, with premieres by the Minnesota Orchestra and the City of Birmingham Symphony Orchestra.
