Music titan Quincy Jones dies aged 91

American music producer Quincy Jones, known for working with the likes of Frank Sinatra, has died aged 91.

The man known simply as "Q" was a huge influence on American music in his work with artists ranging from Count Basie to Frank Sinatra and reshaped pop music in his collaborations with Michael Jackson.

Jones died on Sunday, his publicist said.

There was very little Jones did not do in a music career of more than 65 years. He was a trumpeter, bandleader, arranger, composer, producer and winner of 27 Grammy Awards.

A studio workaholic and a virtuoso at handling delicate egos, he shaped recordings by jazz greats such as Miles Davis, produced Sinatra, and put together the superstar ensemble that recorded the 1985 fund-raiser We Are the World, the biggest hit song of its time.

Jones also was a prolific writer of movie scores and co-produced the film The Color Purple, as well as the 1990s television show "The Fresh Prince of Bel-Air, which launched the career of Will Smith.

Jones' circle of friends included some of the best known figures of the 20th century. He dined with Pablo Picasso, met Pope John Paul II, helped Nelson Mandela celebrate his 90th birthday and once retreated to Marlon Brando's South Pacific island to recover from a breakdown.

Everything he did was stamped with his universal and undeniable hipness. U2 frontman Bono called Jones "the coolest person I've ever met".

Jones' most lasting achievements were in collaboration with Jackson. They made three landmark albums - Off the Wall in 1979, Thriller in 1982, and Bad in 1987 - that changed the landscape of American popular music. Thriller sold as many as 70 million copies, with six of the nine songs on the album becoming top 10 singles.
