Ah yeah, you tend to like those real harsh genesis tones! this composer duo is interesting because, as you say, they haven’t done too much else, though one of them worked on linda3 I guess, which is something.
While we’re on the mega drive subject, I was just listening to the Demolition Man soundtrack. It’s done with the much-maligned GEMS driver, but you can tell composer Nathan Grigg knew what he was doing.
I have a larger thought about this that I’ll share in a separate post eventually, but I never really thought of these “instruments” as guitars, or trumpets, or whatever else, I thought of them as just genesis sounds, basically until adulthood. And I like it better that way!
