Lil Peep, an emerging singer and YouTube star whose debut full-length album dropped in recent months, has died according to multiple reports. The Long Beach, New York-raised emo/hip-hop artist (real name Gustav Åhr) was just 21 years of age.

Lil Peep‘s exact cause of death is still unknown, but is presumed to be from an overdose, most likely from Xanax, Tucson PD spokesperson, Sgt. Pete Dugan, told The News.

Just before 9 p.m., a 911 call was made after a manager, who hadn’t seen Lil Peep in several hours, went to check on him on his tour bus outside The Rock club where he was scheduled to perform last night. Dugan stated that detectives discovered drug paraphernalia around Lil Peep on the bus and that the Tucson Fire Department was unsuccessful in resuscitating the performer at the scene.

Sarah Stennett, the CEO of Lil Peep’s management company First Access Entertainment, said in a statement that she was “shocked and heartbroken” by his death.

“I do not believe Peep wanted to die. He had big goals and dreams for the future which he had shared with me, his team, his family and his friends,” Stennett wrote.

“He was highly intelligent, hugely creative, massively charismatic, gentle and charming. He had huge ambition and his career was flourishing,” she continued.

In January of this year, Pitchfork ran a profile of Peep calling him “the future of emo,” and many credited him with renewing the genre, which had been seen as fading. His debut album Come Over When You’re Sober Part I was released in August, and he described it as “the best project that I’ve made to date.”

Artists from all genres, including Sam Smith, Diplo, and Travis Barker have come forward to offer condolences and thoughts about Peep. Check out their tributes below.
