Seven-time Grammy Award-winning jazz and pop singer Al Jarreau has died in Los Angeles at the age of 76, his publicist says.
The cause of his death was not mentioned. He was in a hospital being treated for exhaustion.
He was one of few artists to have won a Grammy in jazz, pop and R&B categories.
He also wrote the theme for hit television show Moonlighting.
Earlier this month, he retired from touring after more than 50 years.
Born in Milwaukee, Wisconsin, in 1940, he began singing as a child, joining his family in church concerts and events.
But his career took much longer to take off – first, he graduated in psychology and worked at a rehabilitation centre in San Francisco.
His first album, We Got By, was released in 1975 and earned him a German Grammy.
He won his seventh Grammy in 2007
One year later, he released Glow, with which he also won a German Grammy. In 1977, he released a live album, Look to the Rainbow, which got him his first Grammy for best jazz singer.
He was awarded again one year later, this time for the album All Fly Home.
He then crossed over into pop, and in 1981, released Breakin Away, which included the hit We’re in This Love Together, which shot him to fame.
Another Grammy came in, this time as best pop singer.
Finally, his 1992 Heaven and Earth album earned him a Grammy for best R&B vocal performance, meaning he had prizes in the three categories.
Jarreau retired from touring earlier this month due to his health reasons
According to a post on the star’s Twitter profile, his son had recently caught Jarreau singing Moonlighting to one of the nurses in hospital.
Jarreau had suffered health problems in recent years and was hospitalised in 2010 for respiratory problems when touring in France.
A statement on his website read: “His 2nd priority in life was music. There was no 3rd. His 1st priority, far ahead of the other, was healing or comforting anyone in need.
“Whether it was emotional pain, or physical discomfort, or any other cause of suffering, he needed to put our minds at ease and our hearts at rest.”
