Wifisfuneral originally went by the moniker Izzy Kills, then Casper Winter Jacket, then Mozart LaFleur.
Before Isaiah Rivera was famously known as Wifisfuneral, he originally went by the moniker Izzy Kills (also stylized Izzy kill$), eventually Casper Winter Jacket, then Mozart LaFleur before settling on Wififuneral. During an interview with HotNewHipHop, Wififuneral revealed “The first rap name I ever went by was Izzy Kills. (Laughs) I can't believe I'm talking about this shit right now. And then it was Casper Winter Jacket. And then, Mozart LaFleur. That was fire, I don't give a fuck what nobody says. And then I was trying to really come up with something that I'm like “bruh, niggas gotta know who I am.”
He continued saying “I called [Gabe] one day – I woke up at like 11 in the morning – I called him and was like, “what do you think about Wifisfuneral?” And he was like, “that actually sounds kind of hard.” And it took a minute for it to pick up on people, because when people heard my name at first they'd be like, “so your internet is dead? What are you talking about?”
Since then Izzy Kills was known as Wififuneral.
