Canned Heat

Wikipedia - "Canned Heat is a blues-rock/boogie rock band that formed in Los Angeles, California, USA, in 1965. 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'."
