Story highlights

He was an emerging voice on the music scene

The Long Island rapper and singer blended emo and hip hop for a distinctive singing and rapping style

(CNN) —  

Rapper Lil Peep, an emerging voice on the hip hop scene and a YouTube star, has died at the age of 21, police and a business associate confirmed to CNN Thursday.

A spokesman for the Tucson, Arizona, Police Department told CNN that police were called just before 9 p.m. (11 p.m. ET) Wednesday night after Lil Peep was found unresponsive by his manager in his tour bus and said that first responders “rendered medical aid but they were unable to save him.”

“After speaking with people on scene and going into the tour bus, (police) said that there was evidence of a possible drug overdose, most likely from Xanax,” Sgt. Pete Dugan told CNN in a phone interview Thursday.

“Obviously, we’re not medical examiners, so there will be an autopsy to determine the exact cause of death,” Dugan said, adding that there was “no sign of any kind of foul play” and police are “treating it as a suspicious death case, most likely from an overdose.”

Born Gustav Åhr, the Long Island rapper and singer blended emo and hip hop for a distinctive singing and rapping style which often highlighted his drug use.

Many fans first discovered him via the streaming service Soundcloud, where he was one of its biggest stars.

Sarah Stennett, chief executive officer of First Access Entertainment, which partnered with the rapper last year, said in a statement to CNN that she was “shocked and heartbroken.”

“I do not believe Peep wanted to die, this is so tragic. He had big goals and dreams for the future which he had shared with me, his team, his family and his friends,” she said. “He was highly intelligent, hugely creative, massively charismatic, gentle and charming. He had huge ambition and his career was flourishing.”

“I have spoken to his mother and she asked me to convey that she is very, very proud of him and everything he was able to achieve in his short life,” Stennett’s statement said. “She is truly grateful to the fans and the people who have supported and loved him.”

In June, the New York Times described the rapper in an article as having “evolved into something like the scene’s Kurt Cobain, with several astonishingly gloomy and diabolically melodic releases, and a body that is in constant flux: hair dyed one color after another, an anarchy sign and the word ‘crybaby’ tattooed on his face.”

“His songs find a middle ground between hip-hop bluster and emo’s bulked-up anxiety, a blend that feels eminently of the moment, and inevitable,” the article stated.

His debut album, “Come Over When You’re Sober (Part One),” dropped on September 1 and found Pitchfork dubbing him an “emo rap alchemist.

“Peep’s philosophies are no more profound than a great Instagram caption, and he can come off as a bit of an indignant kid, but it’s easy to see why a new class of spitfires are using him as a talisman for their anxieties,” Sheldon Pearce wrote for Pitchfork.

On Thursday, members of the hip hop community, including rappers Lil Yachty and Ty Dolla $ign, offered their condolences on Twitter.

Lil Yachty tweeted “R.I.P. Lil Peep Dawg.”
