Canned Heat is an American rock band formed in Los Angeles in 1965. The group has been noted for its interpretations of blues material and for its efforts to promote 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 and later Harvey Mandel (lead guitar), Larry Taylor (bass), and Adolfo de la Parra (drums).
