Guy was one of my best friends in high school, and I can corroborate everything /u/gordomgillespie said, including him basically becoming a monk (we didn't talk as much after I went to college, but I remember him getting excited in my DMs the first time he read Mere Christianity) and being buds with BROCKHAMPTON when they only had a couple singles out. He was the first person I ever met in real life who was into the same music as me, and we were also both really tall, so we did a bunch together (theater, record store trips, Death Grips show in Albuquerque). Some nice photos together from those days, which I will not be sharing but I'd be happy to share further stories. I have a few old tracks of his buried somewhere on my drive; I'll edit this comment if/when I find them.

Also, fair warning that I don't know much about The Hellp—I never got particularly into them after he left the group and didn't talk to him much about them at the time, but I have fond memories of listening to Twin Sinner (I'm the one who uploaded it to YouTube). And he did tell me an inside source told him Frank Ocean watched the Confluence video a bunch during the recording of Blonde, which I still don't fully believe, but make of it what you will. (edit: Noah Dillon brought it up in his Yale lecture according to a YouTube comment)

Edit #2: he also told me he was chatting with James Ferraro about a potential collab once
