O.B.L.A’s latest single, “All I Know” finds the rapper telling the world everything that he’s learned in the streets and how it has his mindset stuck in those bad ways. O.B.L.A is rapper from Chicago’s Westside (Humboldt Park). He started rapping around the age of 15 but didn’t professionally release his first track until 2016. From then on, he’s released few but spot on tracks. Who knows what he will drop in these upcoming months but just know that he will execute.
