A very quick session with WavePad resulted in this. It's Rayman's theme music, with the speed and pitch (I think, I'm not sure to be honest) set at 50%, with the Bad Rayman chases from the PS1 version of Rayman 1 playing in the background (first the first variation, then the second, then the first, etc). Henchman 800's theme music, also with speed and pitch (?) set to 50%, is also playing the background, with the volume also set to 50%. And, occasionally, I put those 'alarm-like sounds' from Razorwife's theme music in the background, also with speed and pitch (?) set to 50%.
It sounds kind of messy, but that was the general idea. A bit chaotic, gloomy, but also sort of 'relaxing', if one could call it that. Hmm, anyway, opinions?
