Many of the great blues artists of the deeper past recorded albums in the later 1960s. Given the adoration of them from all of the big British bands and US bands like Canned Heat there was certainly an interest. I love these records like Muddy Waters After The Rain. They have such rawness. I Am The Blues is certainly no exception.

Wiki: Four of the nine songs on I Am the Blues – "Back Door Man", "Spoonful", "I Ain't Superstitious", "The Little Red Rooster" – were originally performed by Howlin' Wolf. "Back Door Man" and "Spoonful" were recorded by Howlin' Wolf in June 1960 featuring bass work by Willie Dixon, piano work by Otis Spann, drum work by Fred Below, and guitar work by Hubert Sumlin. "The Little Red Rooster" was recorded in June 1961 with guitar work by Howlin' Wolf and Hubert Sumlin, piano work by Johnny Jones, bass work by Dixon, and drum work by Sam Lay. "I Ain't Superstitious" was recorded in December 1961 with Howlin' Wolf, Hubert Sumlin, and Jimmy Rogers on guitar, Henry Gray on piano, Willie Dixon on bass, and Sam Lay on drums. Full article
