This fan mashup for Tron Legacy re-soundtracks the upcoming movie's trailer with some impressive sound design created in Ableton Live.
Stripped the original audio and redid all of the sound from scratch using Reason/NI Reakto/Ableton Live 8. An M-Audio Axiom 49 was used to perform the Lightcycle Engine Oscillations. I'm sorry for the lack of dialog at the end.. there was no way to cut around it with the score over the top.
