Miller has had a long history with substance abuse, especially following his breakup with Ariana Grande earlier this year.
Mac Miller performs on Camp Stage during day 1 of Camp Flog Gnaw Carnival 2017 at Exposition Park on October 28, 2017 in Los Angeles, California. Throughout his prolific career he collaborated with Anderson.Paak, Ty Dolla Sign, Ariana Grande, Flying Lotus, Thundercat, Kendrick Lamar, and many more.
Friends and fellow musicians have begun to pay tribute to Miller, with Chance The Rapper saying that he is devastated by the news.
Miller had just been preparing to embark on a USA tour after releasing his most recent album, Swimming, on August 3. "I will continue to pray from the bottom of my heart that he figures it all out and that any other woman in this position does as well", she said.
In the video clips, the rapper - whose two-year relationship with Ariana ended in May - showed a turntable that played his track "So It Goes". Great man. I loved him for real.
His most recent album, Swimming, was posted to online streaming services as recently as 3 August.
Just Thursday, Vulture published a profile of Miller. That's fine, that's good, that's life. "God knows, I came close - don't try this at home". I wish it started tomorrow.
Miller told The Associated Press that year that the album's depth and quality reflected two years of warp-speed development, his move from Pittsburgh to Los Angeles and just how serious he was about the craft.
