Rock ‘n’ roll pioneer Little Richard died Saturday morning in his Nashville home at the age of 87, the artist’s son Danny Penniman confirmed to Rolling Stone.

His cause of death is currently unknown.

Considered a founding father of rock ‘n’ roll, Little Richard — born Richard Wayne Penniman in 1932 — landed his first record deal with RCA in 1951. He quickly soared to fame with hits such as “Tutti Frutti,” “Long Tall Sally,” “Rip It Up,” “Lucille” and “Good Golly Miss Molly.”

Known for his eccentric style, gospel-influenced vocals and high-energy piano riffs, he was one of the 10 original inductees into the Rock and Roll Hall of Fame in 1986 and received a Lifetime Achievement Award at the Grammys in 1993.
