Prozzäk was a Canadian pop music duo that consisted of Jay Levine (voice of Simon) and James Bryan McCollum (voice of Milo). Simon and Milo were initially enemies (and I mean enemies) and they fought each other in a war called "Ochiyaki". The war lasted for more than 20 years. But then some funky voice was like "hey you guys are actually best friends!!!" and now they're on a mission to find their true love through their music. At least they were on a mission like that, you know, because Prozzäk disbanded in 2019.
Simon tells stories that represent Jay Levine's life, real life. I don't know if I want to talk about that because I'm not exactly comfortable with talking about the lives of strangers behind their backs but uh. "Anna-Lisa" makes references to his parents' divorce. There, that's all I'll say.
