Clive Davis, music mogul behind Whitney Houston and Bruce Springsteen, dies aged 94

Clive Davis, one of the most influential music executives in the history of rock and pop, has died at the age of 94.

A former head of Colombia and Arista Records, he signed and shaped the careers of artists including Aretha Franklin, Bruce Springsteen, Billy Joel, Whitney Houston, Santana, Janis Joplin, Christina Aguilera, Alicia Keys and many others.

He had recently been in hospital with respiratory problems and was recovering at home in Manhattan, New York, when he died, his family said.

"To the world, our father was the iconic music legend whose vision, instincts, and relentless pursuit of excellence shaped the soundtrack of countless lives," they said in a statement.

"He discovered, mentored, and championed the greatest artists in modern music history, leaving an indelible mark on culture that will endure for generations.

"To his family, Clive was Dad and Granddaddy, the steady presence at the centre of our lives, the source of wisdom, strength, encouragement, and unconditional love."

Born in Brooklyn on 4 April, 1932, he grew up in the Crown Heights neighbourhood.

He graduated from Harvard Law School and had no knowledge of the music industry when he took a job at Columbia Records at the age of 28 - but he took night classes to educate himself on copyright law, contracts and litigation.

Davis used that knowledge to help defeat a federal antitrust suit over Columbia's mail-order record club; and handled delicate contract talks with young stars like Bob Dylan and Barbra Streisand.

He was promoted to vice president of the record label in 1965 and shortly after became president. Among the acts he signed were Santana, Aerosmith, Pink Floyd and Springsteen, giving the label a new lease of life.

"I didn't necessarily have an ear, but I think I developed one," he later said.

"Whether there was a natural ear that was triggered, I don't know the answer to that. But when you see a Joplin or a Springsteen, you know."

He had a reputation for supporting artists, but his decisions could sometimes ruffle feathers.

After a playback for Simon and Garfunkel's fifth album in 1970, he told the "aghast" artists that Cecilia shouldn't be the first single.

"I felt Cecilia would be a hit but Bridge [Over Troubled Water] was something more," he later told Simon's biographer Robert Hilburn.

"Yes, it was a ballad; yes, it was lengthy," he added, in a separate interview with the New York Times.

"But you've got to know when you have a home run. You can't play everything by the rules."

That midas touch paid dividends throughout his career - but it was often fuelled by hard work.

After signing Whitney Houston in 1983, when she was just 19 years old, Davis spent two years hunting for producers and writers who could make the most of her voice.
