American Blues were a 1960s Texas-based garage band who played a psychedelic style of blues rock music influenced by the 13th Floor Elevators. They are most famous for including two future members of the band ZZ Top in their ranks, Dusty Hill and Frank Beard. From 1966 to 1968, they played the Dallas-Fort Worth-Houston circuit and headlined in three clubs all called "The Cellar", in Dallas at clubs such as "The Walrus" on Mockingbird Lane, and in Houston at "Love Street Light Circus Feel Good Machine" on Allen's Landing, as late as 1968.

Around 1968 the band (the two Hill brothers and Beard) decided to leave the Dallas–Fort Worth area, relocating to Houston. At this time, however, guitarist Rocky Hill wanted to focus on "straight blues", while his brother Dusty wanted the band to rock more. Rocky left the band, and the remaining two members joined the recently formed ZZ Top.
