Markeyvius LaShun Cathey (born August 3, 1997), known professionally as Key Glock, is an American rapper, songwriter, and record producer. The cousin of late Memphis rapper Young Dolph, Cathey signed with his record label, Paper Route Empire, to release his commercial mixtape, Glock Season (2017). His debut studio album, Yellow Tape (2020), peaked at number 14 on the Billboard 200 and received gold certification by the Recording Industry Association of America (RIAA). His second album, Yellow Tape 2 (2021), peaked at number seven on the chart and spawned the multi-platinum-certified single "Ambition for Cash", as well as "Proud", which was released in the wake of Dolph's death and marked his first entry on the Billboard Hot 100. His third album, Glockoma 2 (2023), spawned the sleeper hit single "Let's Go"—his second entry on the chart.
Early life Markeyvius LaShun Cathey was born in South Memphis on August 3, 1997. When he was 20 months old, his mother Tameika Cathey was sent to prison, where she would be for the next 15 years. His father was in and out of his life, so he was raised by his grandmother and his aunt. According to Cathey, he and his grandmother occasionally visited his mother in prison during his youth. At 18 years old, he was charged with three counts of aggravated assault related to his involvement in a shooting. Music was a distraction from his oftentimes tumultuous life.
Cathey said he grew up listening to Gucci Mane, Lil Wayne, and cites Three 6 Mafia as his largest influence. He was also a big fan of Project Pat, whom he describes as the "Drake of Memphis". According to Glock, Pat's songs "If You Ain't From My Hood" and "Gorilla Pimp" changed his life. The latter's chorus inspired one of his breakout songs, "Dig That". The first track that Glock recorded himself was a freestyle of DJ Drama's 2011 song "Ain't No Way Around It".
