Roots of Duane Allman

Delaney & Bonnie were an American duo of singer-songwriters Delaney Bramlett and Bonnie Bramlett. In 1969 and 1970, they fronted a rock/soul ensemble, Delaney & Bonnie and Friends, whose members at different times included Duane Allman, Gregg Allman, Eric Clapton, George Harrison, Leon Russell, Bobby Whitlock, Dave Mason, Steve Howe, Rita Coolidge, and King Curtis.

Riley B. King, known professionally as B. B. King, was an American blues guitarist, singer, songwriter, and record producer. He introduced a sophisticated style of soloing based on fluid string bending, shimmering vibrato, and staccato picking that influenced many later electric guitar blues players. AllMusic recognized King as "the single most important electric guitarist of the last half of the 20th century".

Elmore James was an American blues guitarist, singer, songwriter, and bandleader. Noted for his use of loud amplification and his stirring voice, James was inducted into the Rock and Roll Hall of Fame in 1992. His slide guitar technique earned him the nickname "King of the Slide Guitar".

"Nobody Knows You When You're Down and Out" is a blues standard written by pianist Jimmie Cox in 1923 and originally performed in a Vaudeville-blues style in the aftermath of the 1920–1921 U.S. economic depression. A later 1929 recording by Bessie Smith became popular during the early years of the Great Depression due to the lyrics highlighting the fleeting nature of material wealth and the friendships that come and go with it. Since Smith's 1929 recording, the song has been interpreted by numerous musicians in a variety of styles.
