According to the blurb on "Bank Teller"'s YouTube page, the song was "recorded on 03 Greedo's last night home before turning himself in to serve 20 years." Also present in the studio that night were Lil Pump, Lil Uzi Vert, Smokepurpp, and West coat rapper Desto Dubb. The song they made together can be heard above.
03 Greedo was sentenced to his lengthy prison stint in April and started his time inside over the summer. He released his final album as a free man, God Level, in June.
Lil Pump is also currently in jail after violating the terms of his probation earlier this month. Lil Uzi Vert, meanwhile, recently returned with new music in the shape of "New Patek."
