Bobby Womack, a colorful and highly influential R&B singer-songwriter who influenced artists from the Rolling Stones to Damon Albarn, has died. He was 70.

Womack's publicist Sonya Kolowrat said Friday that the singer had died, but she could provide no other details.

With an incomparable voice few could match, Womack was a stirring singer and guitarist in his own right and a powerful songwriter whose hits like "Across 110th Street," ''If You Think You're Lonely Now" and "I Wish He Didn't Trust Me So Much" captured the imagination of future stars in rock 'n' roll and R&B.

"He had a style that nobody else could ever capture," longtime friend, gospel singer Candi Staton, said in a statement. "I loved him and I will miss him so, so very much."

Womack's death comes as something of a surprise. Though he was diagnosed with Alzheimer's disease two years ago and overcame addiction and multiple health issues, including prostate and colon cancer, recently, he seemed in good health and spirits when he performed earlier this month at the Bonnaroo Music & Arts Festival.

He told the BBC in 2013 the Alzheimer's diagnosis came after he began having difficulty remembering his songs and the names of people he had worked with.

And there have been many. The soul singer cut a wide path through the music business as a performer and songwriter in a career that spanned seven decades. Womack was inducted into the Rock and Roll Hall of Fame in 2009, long after he'd lost his fortune and his career to addiction.
