Mac Miller, the 26-year-old rapper known for his canny wordplay and artistic reinvention, died Friday at his Los Angeles home. The apparent cause of death was a drug overdose.

“Malcolm McCormick, known and adored by fans as Mac Miller, has tragically passed away at the age of 26,” his family said in a statement. “He was a bright light in this world for his family, friends and fans. Thank you for your prayers. Please respect our privacy. There are no further details as to the cause of his death at this time.”

While initially counted as a member of the frat-rap genre of the early 2010s, Miller’s career was defined by a refusal to fit in an artistic box. He transitioned from party rap to heady backpacker lyricism to jazz-inflected songwriting in his final two albums. To do so, he often turned away from guaranteed commercial success in favor of experimentation and craftsmanship in his work.

Miller, whose real name is Malcolm McCormick, had publicly struggled with substance abuse throughout his career, and had a well-publicized DUI arrest in May of this year. Miller had been open about his addiction issues in the past, and had discussed his dependence on lean — a combination of codeine and promethazine — extensively. After a years-long period of sobriety, he began to drink again. According to tweets from his ex-girlfriend Ariana Grande, his substance abuse was a reason the pair broke up after two years.  “I am not a babysitter or a mother and no woman should feel that they need to be,” she wrote. “I have cared for him and tried to support his sobriety and prayed for his balance for years (and always will of course).”

Miller was born in Pittsburgh in 1992, and first broke onto the hip-hop scene when he began rapping at 14 under the alias EZ Mac. He quickly racked up an enormous following as a good-natured, preternaturally talented wordsmith while still in his teens, releasing a series of mixtapes.

By 2010, he’d ditched the moniker for the simpler Mac Miller, and signed with Rostrum Records, the label of fellow Pittsburgh rapper Wiz Khalifa, whose career was burgeoning at the time. Miller found wild success in the era of hip-hop blogs as a rapper that catered to fans in his direct demographic: young, and looking to have fun. Among his earliest hits was “Donald Trump,” a light-hearted song that would lead to a feud between Miller and the now-President. That song would be followed by Blue Slide Park, Miller’s 2011 debut album named after Frick Park in Pittsburgh. The album was a commercial smash, receiving disappointing reviews but debuting at Number One on the Billboard charts.

Miller’s peers shared their memories and condolences of the rappers following his death. “Praying for Mac’s family and that he rest easy,” tweeted fellow Pittsburgh rapper and former labelmate. Chance The Rapper also tweeted his condolences: “Mac Miller took me on my second tour ever. But beyond helping me launch my career he was one of the sweetest guys I ever knew. Great man. I loved him for real. Im completely broken. God bless him.” “Rest in your peace Mac Miller,” wrote Solange Knowles. “Always exuded so much kindness and goodness. Than you for sharing your gifts with us all.”

In an interview with New York‘s Craig Jenkins, Miller frankly addressed his mental health and substance abuse issues. ““I really wouldn’t want just happiness, and I don’t want just sadness either,” he said. “I don’t want to be depressed. I want to be able to have good days and bad days.”
