This delightful concert collaboration is about the most fun you can have without breaking any laws. Natural, romantic and relaxed, but truly energized, there is a whiff of old-world danger about it. Nelson has always been a fan of classic swing and blues and he lets loose here, even playing some sly honky-tonk and Gypsy jazz guitar. For his part, Wynton frees himself from any obligation he has to be "important" and just has a great time. You can't suppress the joy heard here -- if we could feel this way without music, this set wouldn't need to exist. Thank Willie and Wynton that it does.
