According to his website, Allman is survived by "his wife, Shannon Allman; his children, Devon, Elijah Blue, Delilah Island Kurtom and Layla Brooklyn Allman; three grandchildren; his niece, Galadrielle Allman; lifelong friend Chank Middleton, and a large extended family". "Playing music lifted him up and kept him going during the toughest of times", the announcement said.
Allman formed The Allman Brothers Band in 1969 in Jacksonville, Florida, with his older brother Duane, guitarist Dickey Betts, bassist Berry Oakley Jr., and drummers Butch Trucks and Jai Johanny "Jaimoe" Johanson.
Allman tried to reboot the band several times throughout the rest of his life and found hit-and-miss commercial success, particularly with the 1987 hit "I'm No Angel". Allman fell into the depths of alcoholism and heroin additcion and went through a string of marriages, most notably to pop star Cher from 1975-79.
Allman continued recording and touring, both with reunited versions of the Allmans Brothers Band and with his own bands, for some 40 years.
The musician, who founded The Allman Brothers Band with his brother, Duane, died at age 69, a statement on his website confirms.
Still, Allman had been suffering from ill health in recent years, dealing with a respiratory infection, a hernia, a liver transplant and an irregular heartbeat.
The legendary Allman Brothers Band singer, organist and songwriter recently cancelled all his 2017 dates due to health concerns. "He was a kind and gentle soul with the best laugh I ever heard".
Lehman told NPR News Allman had finished a new album, which would be released in September. His love for his family and bandmates was passionate as was the love he had for his extraordinary fans. "We will all miss him".
Allman was awarded the Grammy Lifetime Achievement Award in 2012.
