The American soul singer, Ike Turner, has died at his home in California at the age of 76.
Turner, regarded as one of the pioneering figures of rock'n' roll, was best known for his musical partnership with, and stormy marriage to, Tina Turner.
His cause of death was not immediately known, said his manager, Scott Hanover.
Turner managed to rehabilitate his image somewhat in later years, touring around the globe with his band the Kings of Rhythm and drawing critical acclaim for his work.
He won a Grammy in 2007 in the traditional blues album category for 'Risin' with the Blues'.
He shared his only other Grammy with Tina Turner in 1972 for their cover of 'Proud Mary'.
Michele Schweitzer, a spokeswoman for his former wife, said: "Tina is aware that Ike passed away earlier today.
"She has not had any contact with him in 35 years. No further comment will be made."
Turner is credited by many music historians with making the first rock 'n' roll record, 'Rocket 88', in 1951.
