Even back in the 90s there were plenty of non-Japanese artists putting anime/manga artwork on their releases all throughout the underground electronic music scene. I don't think there was any big reason as to why, it's most likely because the type of guys who wanted to make jungle/digital hardcore/gabber/breakcore/IDM/drill & bass/techstep/whateverhtefuckcorestep were nerds and anime was gaining a wider global audience in a post-Akira age.
