Mac Dr John Rebennack playing songs from the canon of Duke Ellington is as natural as the break of day. But the gris-gris king interprets Ellington in a way unlike anyone else. "Mood Indigo", arranged for Dr. John's six-man New Orleans group, takes on a fresh, heartfelt immediacy with the good doctor's vocals and piano locked into a relaxed groove. He sings another slice of essential Ellingtonia, "Do Nothing 'Til You Hear from Me", with a lighthearted nonchalance that epitomises the worthiest New Orleans performers. Dr. John packages snippets of his keyboard playing as panaceas for the soul on a funked-up interpretation of "Caravan", even spinning off on a "Wade in the Water" tangent before wrapping up the song. But with so many Duke Ellington nuggets to dust off for reinterpretation, one wonders why Dr. John elected to go with popular numbers that get covered again and again. To his credit, he does serve up the lesser-known "The Flaming Sword", where his piano is luminous in the Calypso fashion of Professor Longhair, and he offers delightful, funkified updates of the Ellington obscurities "On the Wrong Side of the Railroad Tracks" and "I'm Gonna Go Fishin'". --Frank-John Hadley
