It is easy to forget that Tupac Shakur's career only lasted five years.
The rapper released his first studio album "2Pacalypse Now" in November 1991. By September 13, 1996, he was dead. Shakur was just 25 when he was gunned down on a Las Vegas street and succumbed to his injuries days later.
Within those five years, Shakur was in the studio recording the trove of music he left behind. He had roles in films like "Poetic Justice" and "Above the Rim." And as Shakur's fame grew, so did his controversial reputation, reports CNN.
Twenty years after his death, there continues to be a fascination with Shakur. With his artistry cut short, some wonder if the rapper was on the verge of reaching his full potential just as he was killed - writing about #BlackLivesMatter decades before its time.
Writer Kevin Powell covered Shakur extensively. In 1995, Powell conducted the now famous Rikers Island interview with Shakur where the rapper was imprisoned after being accused of rape (he was found guilty of sexual abuse and served eight months).
Powell said in death, Tupac is now an even bigger star.
"When you are in the middle of it, you are not thinking global, iconic figure on the level of a Bob Marley, a Nina Simone, the Beatles or Elvis," Powell told CNN. "I'm talking not just hip hop but globally. I have traveled all over this country and around the world and everywhere I have gone, his name comes up in some form or fashion."
The writer recounts some of his relationship with Shakur in his book "The Education of Kevin Powell: A Boy's Journey into Manhood." Powell said he credits Shakur's enduring legacy to the rapper's vulnerability, honesty and authenticity.
"Pac was a street poet and he spoke for the people in the hood," Powell said. "He was constantly pushing the limits of what an artist could do in the tradition of a Marvin Gaye, Bob Dylan and Nina Simone."
Last year, Ebony magazine ran a collection of Shakur quotes and poems under the headline: "Tell Me What's A Black Life Worth: 2Pac on #BlackLivesMatter." (The article was tied to a Grammy Museum exhibit titled "All Eyez On Me: The Writings of Tupac Shakur.")
Powell said he absolutely believes that "Pac would have grown into someone who would have talked about race, gender and various forms of discrimination."
Beyond being an actor and wildly successful hip hop artist, Shakur was well known for his encounters with the law (the rappers were murdered within six months of each other.)
There are plenty of conspiracy theorists who don't believe that Shakur is dead. Since his shooting, there have been whisperings that Shakur faked his own death after he was hospitalized.
Recently, a video has been circulating on social media which claims to "prove" Shakur is alive. Fans have continued to share the video despite it being debunked.
Kading said he's heard countless theories - including one about a government conspiracy connected to Shakur's death.
"That's salacious to the audience and they want to think there is much more to the story [of Shakur's death]," Kading said. "And of course there are these racial overtones that have to do with [theories that] the government trying to suppress these artists because of where they were potentially going with the black movement. When you know the facts of the story, that's all far fetched. But I think that's what keeps it appealing and mysterious."
