Dr. John原名Mac Rebennack，有“钢琴鬼才”之称，是“新奥尔良之声”后期的代表人物，和The Meters基本同时期。Dr. John本来是新奥尔良的一个钢琴师，专门给人伴奏的，不过他的才华在一次录制中被Phil Spector发掘出来，于是开始发表自己的作品。这张专辑被认为是swamp-funk的经典。 　　这张专辑在滚石杂志选出的500张历代最强专辑中排名第143位。 　　The most exploratory and psychedelic outing of Dr. John's career, a one-of-a-kind fusion of New Orleans Mardi Gras R&B and voodoo mysticism. Great rasping, bluesy vocals, soulful backup singers, and eerie melodies on flute, sax, and clarinet, as well as odd Middle Eastern-like chanting and mandolin runs. It's got the setting of a strange religious ritual, but the mood is far more joyous than solemn.
