Henry Thomas was an American country blues singer, songster and musician. Although his recording career, in the late 1920s, was brief, Thomas influenced performers including Bob Dylan, Taj Mahal, the Lovin' Spoonful, the Grateful Dead, and Canned Heat. Often billed as "Ragtime Texas", Thomas's style is an early example of what later became known as Texas blues guitar.

Canned Heat is an American blues and rock band that was formed in Los Angeles in 1965. The group has been noted for its efforts to promote interest in blues 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 of Hite (vocals), Wilson, Henry Vestine and later Harvey Mandel, Larry Taylor (bass), and Adolfo de la Parra (drums).
