We were just together working throughout the whole process and there was never a point where the orchestra was not in their minds and the electronics were not in my mind. I was locked in a room with robots for almost two years and it was simply a lot of hard work. It seems complicated at the end of the day, but it’s actually quite simple. Trapanese cited the collaboration between the different genres to work out well in the end, stating:

The orchestra was conducted by Gavin Greenaway. The band collaborated with him for two years on the score, from pre-production to completion.

Daft Punk's score was arranged and orchestrated by Joseph Trapanese, who stated he is a fan of Daft Punk as a duo and as solo artists. Kosinski stated that the score is intended to be a mixture of orchestral and electronic music. The score of Tron: Legacy features an 85-piece orchestra, recorded at AIR Lyndhurst Studios in London. Noé had asked Bangalter to compose the soundtrack to the film Enter the Void, but Bangalter was working on Tron: Legacy at the time and instead served as sound effects director.

Thomas Bangalter of Daft Punk had previously produced the soundtrack to Gaspar Noé's 2002 film Irréversible. When asked why he wished to work with the duo, Kosinski replied, "How could you not at least go to those guys?" The film producers initially attempted to reach Daft Punk in 2007, but the duo had been unavailable due to their Alive 2006/2007 tour. Tron: Legacy director Joseph Kosinski and music supervisor Jason Bentley approached Daft Punk and requested that the duo compose the film score. It is the only film score by French music duo Daft Punk. Without a doubt, it's a game-changer for Daft Punk.Tron: Legacy (Original Motion Picture Soundtrack) is the soundtrack album to the 2010 film of the same name, released by Walt Disney Records on December 3, 2010. These tracks come as welcome relief from the tension Daft Punk ratchets up on almost every other piece, particularly "Rectifier" and "C.L.U." Encompassing the past, present, and future of sci-fi scores, Tron: Legacy feels like it grew and mutated from its origins the same way the film's world did. It's not until the score's second half that the duo's more typical sound emerges on "Derezzed"'s filter-disco and on "End of the Line," where witty 8-bit sounds evoke '80s video games. However, for most of Tron: Legacy, they're concerned with pushing boundaries. Daft Punk get in a few clever nods to Wendy Carlos' Tron score, from "The Grid"'s blobby analog synth tones to "Adagio for Tron"'s mournful sense of lost wonder. Elsewhere, "Recognizer"'s pulsing horns and synths and "The Son of Flynn"'s arpeggios and strings are so tightly knit that they finish each others' phrases. "The Game Has Changed" may be the most dramatic example: It starts with a wistful wisp of melody that sounds like a ghost in the machine, then swells of strings and brass and buzzsaw electronics submerge but never quite overtake it. Working with the London Orchestra, Bangalter and de Homem-Christo fuse electronic and orchestral motifs seamlessly and strikingly. Tron: Legacy's legitimacy as a score may surprise listeners unaware of Bangalter's fine work on 2003's Irreversible while that score actually hews closer to Daft Punk's sound, it showed his potential for crafting music beyond the duo's usual scope. However, Tron: Legacy takes a much darker, more serious approach than the original film and Daft Punk follows suit, delivering soaring and ominous pieces that sound more like modern classical music than any laser tag-meets-roller disco fantasies fans may have had. When it was announced that the duo would score the sequel to one of sci-fi's most visionary movies, it seemed like the perfect fit: Their sleek, neon-tipped, playful aesthetic springs from their love of late-'70s and early-'80s pop culture artifacts like Tron. "The Game Has Changed" is the name of one of the tracks on Daft Punk's score to Tron: Legacy, and it also fits Thomas Bangalter and Guy-Manuel de Homem-Christo's music for the film.
