It was an awesome scene, I used to put out jungle and trip hop tracks on Mono211/Monotonik/Voodoo and a couple of other mod labels back in the day.
Everything was free, in an era where studio time and studio equipment was really expensive it was mind-blowing to be able to do it with just a PC, all in software. Lots of friendly competition between artists and the file format was such that you could open a mod and see exactly how it was put together, and reuse the samples if you wanted to. Gave birth to many people's careers in music and software!
