What if, between the original classic Tron and the upcoming Tron 2: Legacy, there were another Tron movie, lost forever in cinematic history? Between the soaring score by Wendy Carlos for the original and Legacy’s Daft Punk music, what would the soundtrack have sounded like? Of course, it would have absolutely had some Journey in it.

Such a movie was rumored, but as with so many projects, leaves behind no evidence. What if it had left a score you could hear? The mysterious “Flynn 1.5″ writes to share a free, downloadable soundtrack that answers that question.

And you can argue with an album that begins out with “For the Love of ENCOM”? Indeed. You can stream the full album and download all but the Journey remix. Read the full “backstory” after the jump.

Tron moniker or no, the results are some lovely music, featuring the likes of Tiger Mendoza, Team9, artist and CDM regular reader Lilith The Kitten, and ringleader World Famous Audio Hacker, among others. (Trivia – Tiger Mendoza has his own, Creative Commons-licensed album, and Team9 earned notoriety for a mash-up collaboration with Green Day.)

In a Hollywood overrun with remakes, a new Tron has quite a daunting challenge. The original film may be a cult hit for its 80s arcade cool, but it also was a seminal moment in the evolution of computer animation, at the nexus of obsessive-compulsive optical effects that came before and digital effects that came after. (Google Perlin Noise, if you must.) But where the bits of the effects look uneven or dated alongside the brilliant, it’s nearly impossible to top the genius of Wendy Carlos’ score. Her deft blend of choirs, orchestras, organs, and rich electronics wasn’t just forward looking: it’s fresh today, an alternative to some of the signature sameness in today’s games and films.

Perhaps Tron Legacy will do what other belated sequels have not: express love for the original. With Daft Punk helming the score and a reverent, inspired crew ready to make Tron live again, the trailer last week was the real sleeper hit of Comic-Con.

If that’s not enough layers of fandom, though, head to GearSlutz for a lesson in film scoring and a recreation of the trailer in Reason, custom Reaktor patches, and Ableton Live. This is not much of an infomercial for Live: because Ableton’s arrange view doesn’t quite understand frames, scoring with Live is a bit of a beast. (Live 9, anyone?) But it’s a great example of love for the movie and its original score. And hey, everyone need a source of joy, even a film.

Ableton Live for Sound Design :Tron Legacy [GearSlutz forum]

Stripped the original audio and redid all of the sound from scratch using Reason/NI Reaktor/Ableton Live 8. An M-Audio Axiom 49 was used to perform the Lightcycle Engine Oscillations

Wendy Carlos, if you’re out there, we get it. You revolutionized film scoring and electronic orchestration, and we’re all in your debt. It’s not so much that you switched on Bach or switched on Moog or even switched on Kubrick and guys in glowing skin-tight outfits. You switched on sound, and nothing has been quite the same since.

Now, we just have to hope 2010 can show us a good time, too.
