William Guest, a member of Gladys Knight and the Pips, has died.
He was 74.
Guest's sister-in-law, Dhyana Ziegler, said he died Thursday in Detroit of congestive heart failure.
Guest performed throughout the lifespan of the Grammy-winning group from 1953 to 1989.
He performed background vocals on hits such as "I Heard It Through the Grapevine" and "Midnight Train to Georgia."
"My heart is broken, but I know his legacy will live on," said Guest's daughter, Monique Guest, in a statement.
Gladys Knight and the Pips were inducted into the Rock and Roll Hall of Fame in 1996 and the Apollo Hall of Fame in 2006.
