That Duke album is a fantastic place to start.
One of the best jazz composers playing the music of another of the best jazz composers? Can't go wrong.
That's the LP I ordered (from MusicDirect). It was on back order for the better part of two weeks and is now, courtesy of the USPS, somewhere between Chicago and Detroit. It's about a four- or five-hour drive, depending on how you drive. They could've just called me to come pick it up.
