Cutting his teeth on New Orleans session work while still a teen in the 1950s, pianist and singer Dr. John (born Mac Rebennack) emerged in the late 1960s with GRIS-GRIS, a blend of snaky rhythms, Crescent City funk, and swampland voodoo flair. Since then, he has remained one of New Orleans’s prime musical ambassadors, an artist with his own trademark sound and style. These sessions actually have a feeling not unlike his early-'70s work. Most of the titles are self-penned, and there are also a few Professor Longhair covers. If you like vintage Dr. John, this is almost mandatory.
