Livy worked on the music for Sin City II: A Dame to Kill For. She assisted composer Carl Thiel, who scores many of Robert Rodriguez’s projects. For Sin City II, she issued and secured contracts from collaborators to ensure proper copyright-clearance of music recordings. Additionally, the studio received hundreds of music submissions regularly, and she would organize the music and categorize it into a library according to mood, tempo, and which scene type the music would fit into for the film.
