@Amariez10585 kind of a long story, but I will try to summarize. He started doing EDM a long time ago (he ran by another name, The Eden Project), but has since moved to more Indie/Alternative/Pop music. His songs are very emotional and lyrically elaborated. If I had to recommend you three songs, they would be Wake up (might as well give a listen to the whole End Credits EP), Sex (became Tik Tok famous), and Projector (one of my personal favorites). It’s really hard for me to pick just 3 tho, the man has a looot of great music.
If you’re looking for more ways in which he has any relation to Jon, EDEN has done multiple collabs with Illenium, for example!
