First recorded (as “Bull Doze Blues”) by Henry Thomas (1928).
Hit version by Canned Heat (US #11 1969).
From the wiki: “Canned Heat, who were early Blues enthusiasts, based ‘Going Up the Country’ on ‘Bull Doze Blues’, recorded in Chicago for Vocalion Records in 1928 by Texas bluesman Henry Thomas. Thomas was from the songster tradition and had a unique sound, sometimes accompanying himself on quills, an early Afro-American wind instrument similar to panpipes.
“For Canned Heat’s recording ‘Going Up the Country’, Alan Wilson used Thomas’ melody on the quills and his basic rhythm, but re-arranged it for a rock setting and rewrote the lyrics; multi-instrumentalist Jim Horn reproduced Thomas’ quill parts on the flute.
