Here’s a timely bit of audio for Duke Ellington's 113th birthday anniversary today: Duke’s appearance at the 1970 New Orleans Jazz Festival and Louisiana Heritage Fair. It was the third annual jazz festival in New Orleans, but the first that George Wein produced under the Jazz & Heritage banner, and for the occasion Ellington was commissioned to write a new work, The New Orleans Suite. The audio file from Wolfgang's Vault includes only the suite’s opening movement, “Blues for New Orleans,” a showcase for Johnny Hodges and organist Wild Bill Davis. Ellington was notorious for completing new works minutes before deadline, but it would seem that most of the suite must have been ready at the time of the festival appearance on April 25 since its recording for Atlantic Records was completed only 18 days later on May 13. Then again, maybe not.
