Gregg Allman’s final LP Southern Blood will be released posthumously on September 8 and the first track is now available to stream in the form of the song “My Only True Friend.”

Co-written with longtime musical director Scott Sharrard, Rolling Stone notes that the song recalls stories from Allman’s past with brother Duane. “I never told him because I didn’t want to spook him,” Sharrard said of writing the song with Duane in mind. “Since his brother was such an important figure in his life.”

The album also includes a number of covers including the Grateful Dead’s “Black Muddy River” along with songs from Bob Dylan, Little Feat and others. “He loved the guys in the Dead,” Sharrard said of Allman’s relationship with the band. “But I don’t know if that writing style was his bag in general. But he warmed up to the tune and in the end he thought, ‘Man, I kinda love this song.’”
