Grammy-winning rapper Coolio died of a heart attack on Wednesday evening in Los Angeles, his manager Jarel “Jarez” Posey confirmed to TMZ and Rolling Stone. He was 59.

Coolio was visiting a friend when he collapsed and died on the bathroom floor, according to reports.

The rapper, whose real name is Artis Leon Ivey Jr., was best known for his hit singles “Gangsta’s Paradise” and “Fantastic Voyage.”

“Gangsta’s Paradise” sampled Stevie Wonder‘s 1976 song “Pastime Paradise”. Wonder gave his approval to use the sample only if the song did not contain any profanity.

“Gangsta’s Paradise” won the 1996 Grammy for Best Solo Rap Performance and was nominated for a Best Song of the Year Grammy.
