Tulsa's B. Lou initially found fame as a YouTuber, posting reactions to popular rap songs and videos, before he began rapping on his own. Along with his friend JustZik, B. Lou co-founded the YouTube channel ZIAS! in 2013. The channel eventually attracted over two million subscribers, and reaction videos to tracks by XXXTENTACION and Lil Uzi Vert went viral. The duo also uploaded their own rap freestyles, and in 2017 they began releasing remixes of popular tracks by rappers such as Tay-K and YBN Nahmir. "Louie Gang," B. Lou's take on Lil Pump's "Gucci Gang," received a fair amount of attention, and in 2018 B. Lou released the original song "Molly" (featuring Stick Up Starr).
