SAN DIEGO (AP) -- Ike Turner, whose role as one of rock's critical architects was overshadowed by his ogre-like image as the man who brutally abused former wife and rock icon Tina Turner, died today at his home in suburban San Diego. He was 76.

"He did pass away this morning" at his home in San Marcos, in northern San Diego County, said Scott M. Hanover of Thrill Entertainment Group, which managed Turner's musical career.

There was no immediate word on the cause of death, which was first reported by celebrity Web site TMZ.com.

Turner managed to rehabilitate his image somewhat in his 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."

But his image is forever identified as the drug-addicted, wife-abusing husband of Tina Turner. He was hauntingly portrayed by Laurence Fishburne in the movie "What's Love Got To Do With It," based on Tina Turner's autobiography.
