Dr. John, a.k.a. Mac Rebennack, has undergone a number of incarnations in a career that spans nearly 50 years, from the acid-tinge voodoo of his Night Tripper persona to his role as one of New Orleans' most revered champions of American musical tradition.

"Ol' Black Magic" and "Come Rain or Come Shine" are the epitome of sultry style, with Rebennack's trademark ragged, warbling vocals providing his own emotional connection.
