Multi-Grammy Award-winning artist–Amy Winehouse–shocked the music industry when she died on Saturday, alone. She was 27.

According to a report by the U.K. Daily Mail, Winehouse’s death may have been caused by a combination of ecstasy, cocaine, and ketamine which she bought the night before her death. She was also observed to have been drinking heavily which comes as no surprise. Her hit song “Rehab” was even about her problem with drugs and alcohol.

Aside from Winehouse, famous musicians who also died at the age of 27 are:

Brian Jones – the founding member of the Rolling Stones

Janis Joplin – a pioneer for women in 60’s rock music

Jim Morisson – of the Doors

Kurt Cobain – Lead guitarist of Nirvana
