Danny Adler (born 1949) is an American blues-rock guitarist.
After playing with leading Cincinnati musicians, such as Bootsy Collins, Slim Harpo, H-Bomb Ferguson and Albert Washington, in the early 1960s, he went to San Francisco in 1969 to join John Lee Hooker, T-Bone Walker, Solomon Burke, and experimental group Elephant's Memory.
Moving to England in 1971, he founded Roogalator, one of the first signings by the fledgling Stiff Records, as well as appearing regularly with Rocket 88, the back-to-the-roots boogie-woogie band which included Rolling Stones drummer Charlie Watts, Ian Stewart, Jack Bruce and many other leading UK-based musicians.
In 1980 he put together another blues-rock revival band, the De Luxe Blues Band, with Bob Hall, Bob Brunning and Micky Waller. Dick Heckstall-Smith would join soon after. The band originated as a pick-up band to accompany visiting American blues performers Eddie Clearwater and Carey Bell but stayed together for over 12 years and recorded 5 albums. They disbanded when Adler returned to the US, although Brunning would later revive the band with a new lineup.
