Tupac Amaru Shakur made more music in five years than most artists make in a lifetime. Me Against the World was recorded from a prison cell and debuted at number one. All Eyez on Me arrived six months after his release and went platinum six times. The Don Killuminati: The 7 Day Theory was recorded in three days under a different name and dropped two months after he was shot. He was twenty-five years old. The catalog he left behind still sounds unfinished, which is exactly the point.
