It’s not a rhumba. It’s not even really Latin. And the guy who wrote it named it after himself and his father at the same time. This week on The Standard Show — Armando’s Rhumba by Chick Corea. Nine versions. One tune. A Swedish clarinettist, a Romani guitar trio, a Cuban piano legend, and something from the Carolinas that has absolutely no business being as good as it is.
