Beginning with Tron (1982) and followed by Tron: Legacy (2010), the films center around a virtual reality known as "the Grid" and detail the battle between humans and antagonists within the program for power.
Something that fans of Tron: Legacy adored about the film was Daft Punk's score. Known for their electronic music, the group dazzled fans by combining their signature, techno flair with orchestral music, creating the perfect musical backdrop for the electronic, sci-fi adventure in Tron: Legacy.
