Along with "Gris-Gris", Dr. John is perhaps best known for his recordings in the period 1972-74. 1972's "Dr. John's Gumbo", an album covering several New Orleans R&B standards with only one original, is considered a cornerstone of New Orleans music. In his 1994 autobiography, "Under a Hoodoo Moon", Dr. John writes, "In 1972, I recorded "Gumbo", an album that was both a tribute to and my interpretation of the music I had grown up with in New Orleans in the late 1940s and 1950s. I tried to keep a lot of little changes that were characteristic of New Orleans, while working my own funknology on piano and guitar." The lead single from the album, "Iko Iko", broke into the "Billboard" Hot 100 singles chart, eventually reaching #71. In 2003, "Dr. John's Gumbo" was ranked number 404 on "Rolling Stone" magazine's list of the 500 greatest albums of all time.
