If you're good with heavier stuff, Ill Niño is a severely underrated nu metal band. I don't think this is the case for all of their albums, but their debut Revolution Revolucion was released in both Spanish and English.
There's also Bloodywood, an Indian folk metal band who's only recently gotten on my radar. They just released a new album a few days ago called Nu Delhi, which I suggest checking out.
From Japan, I'd recommend BABYMETAL and Maximum The Hormone. The latter is what people online like to refer to as "Japanese System of a Down" lol I've been listening to both of them on-and-off for about 10 years now, and they're pretty solid.
