I'd imagine his legacy kind of died with him. He was really well known at the time, to my understanding, but he never made any huge amounts of progress and seemed to isolate himself from the broader music world pretty hard. If he had lived to produce more I'm sure he'd be a common name but, he kinda took that opportunity away from himself.
You know, it sucks because I both want to hate him and like him at the same time. Like he was really interesting, and certainly the kind of guy I want to like when it comes to his interests. But then, he was also a violent and horrible person. But then again, I have to wonder how much of that comes from being alive during a time when the entire world is against you. I mean, not that it's too much different now, but then it was just straight up illegal for him to even be himself. Add severe mental illness to that, at a time when that also wasn't gonna receive any help short of a lobotomy, and Joe didn't really have many chances in life..
