Keimon Downey-Cowan (born July 14, 1995), better known by his rap alias YSB OG (or formerly Kane Grocerys), is an independent Los Angeles-based rapper hailing from Waukegan, Illinois, a suburb just north of Chicago. He is a member of the collective Goth Money Records.

He started making music at age 16 after the death of his grandfather prompted him to reconsider his life’s path. At this time, he shifted his focus from basketball to art. He later met Black Kray, the leader of Goth Money Records, in LA.

He describes his sound as “trap goth.” The term inspired the name for his debut mixtape. He is also a pioneer in the tread genre.

He changed his name from Kane Grocerys to YSB OG in early 2018.
