There was also another black alt-rock artist, in addition to Darius and Fishbone, who was briefly popular around the late 80's or 90's as I recall. But I'm flaking on his name and songs, and Google isn't helping much. I remember seeing some of his vids on MTV though.
Also since I haven't seen him mentioned
It's worth noting too, when talking about how most people are mentioning English language stuff, until rather recently people's exposure was very much geared towards who was touring (and promoting tours on radio / TV) fairly locally. You just generally don't have a lot of foreign-language touring, especially in the US - so there wasn't that much exposure. Radio didn't play it, TV shows didn't have the bands on, even up to MTV the videos didn't play. That doesn't mean it doesn't exist - it just means on a forum primarily of English speaking Americans it's probably not going to jump to mind. There were plenty of big name British bands that just never made it to the US, and a thriving rock scene in Australia / NZ that practically no one in the Western Hemisphere has ever heard of, simply because touring was impractical.
(Metal is a bit of an exception, perhaps because guttural screams are universal, but even the international metal scene is a fairly recent phenomenon.)
Of course another factor is your non-English rock that did make it internationally is stuff like this:
