(CNN) -- Michael Been of the 1980s alt-rock band The Call -- and father of Black Rebel Motorcycle Club's Robert Been -- died Thursday. He was 60.
The elder Been was on tour in Belgium as the sound engineer for Black Rebel Motorcycle Club when he died of a heart attack backstage, said publicist Juliana Plotkin.
The Call had several hits in the early 80s, including "The Walls Came Down" and "Let the Day Begin," and earned many notable musicians as fans along the way.
Among them were Bono and Peter Gabriel, both of whom contributed to The Call's albums.
In later years, Been played a key role in Black Rebel Motorcycle Club, said Plotkin -- who represents the band.
"Often referenced as their fourth member, Been spent countless hours in the studio acting in many roles from mentor and guide," she said.
