The group has been noted for its own interpretations of blues material as well as for efforts to promote the interest in this type of music and its original artists. It was launched by two blues enthusiasts, Alan Wilson and Bob Hite, who took the name from Tommy Johnson's 1928 "Canned Heat Blues", a song about an alcoholic who had desperately turned to drinking Sterno, generically called "canned heat". After appearances at the Monterey and Woodstock festivals at the end of the 1960s, the band acquired worldwide fame with a lineup consisting of Bob Hite, vocals, Alan Wilson, guitar, harmonica and vocals, Henry Vestine on lead guitar, Larry Taylor on bass, and Adolfo de la Parra on drums.
