To be honest, the other, Dune I, soundtrack is much more a break-through in both electronic and game music. I'm stating this as s.o. with 25 years of deejay experience in various electronic genres, 20 years of various dev experience, and lots of performances. Also as s.o. who witnessed the evolution of pattern-based music since its very start with ModTracker, ScreamTracker II, FastTracker and Impulse Tracker. I've used them all, and what Stephane Picq did with the original soundtrack is just incredible.

Stephane's work is a combination of masterful composition (complex melodies, progressions, not the typical three-notes of the time), engineering (as the tracks are limited in number in the MOD files) and also synthesis (as most of the sounds he produced himself on various hardware). Of course we could expect more from the mastering perspective, but I doubt this OST ever reached mastering level, and besides - most if not all of the eurotrance that got released in the 90s is subpar to these compositions if you play them side-by-side.

The only times people got close to such engineering feat with early PCs and SoundBlaster/Adlib is within the demoscene, where people like John Valtonen (of Future Crew) could pull. We were all watching and listening in total amaze.

It would help to maintain his legacy if the soundtrack was available somewhere. As it stands, the original Amiga release is not available on my usual sources. And I have multiple sources.
