I listened to the first track, Rockin' In Rhythm five or six times before going onto the second track; and experienced the delight of discovering something truly good and remarkable from two artists, about whom I thought I knew everything good and remarkable. Back in the 1970's I collected Ella songbooks on vinyl (Gershwin, Porter, Rogers & Hart), but never got around to the Ellington collection. How fortunate that I inadvertently saved this little gem for a rainy day. Listening to it is like discovering Ellington and Ella anew. Except with the added appreciation of a fan. I would never tire of Rockin' In Rhythm, so reliable a source of joy it is...my soul smiles for the privilege to witness this collaboration.
Output:
Positive
