Syndrome was the name of a composition by New Orleans pianist and father to Wynton and Brandford Marsalis, Mr. Ellis Marsalis. Syndrome first appeared on one of his early albums, if not the first.
Here, with the assistance of a relaxed, grooving trio he performs the same song at the Bern Jazz Festival, 1997. I couldn't identify the bassist and drummer. If you know their name, please update me.
