This album is essentially a best-of for both Johnny and Willie. Musically, it's slightly less than stunning, but it does reveal the fact that Willie could have been one hell of a jazz guitarist. The vocals are what you'd expect.No, the real prize here is hearing the songs stripped down, without production...we get to hear Cash classics like "Don't Take Your Guns To Town" without the intrusion of a producer or a "perfect take." Nelson also benefits with renditions of songs like "Crazy" and "Night Life."And then there's the banter...two old friends bs'ing in front of a studio audience. Wonderful stuff...it'll leave you with a glow in your heart. (We even hear June Carter offstage.) Music fans should look into this. Really. It does get slow once in awhile, but that's my fault, not theirs. Enjoy.
