Your last concert was to see who and when?

I went to see Kansas in Tempe, AZ a couple of weeks ago. I had no desire to see them, but my best concertgoing buddy been nagging me for three years and finally treated me to the show. 
Long story short, I became an instant fan. These guys are musicians, and not just a used up legacy act. Everyone there was completely engaged from the first moment, and during a 2 hour show with no intermission I never saw anyone get up to use the bathroom which was a first for me after 50 years of concerts. They started acoustic then went electric, and even though they were all great, original guitarist Rich Williams stood out as an outstanding player. See them if you can, even if you're a sceptic like I was.     

We saw Kansas a few months ago in Portland and they were fantastic!  I'm not a huge fan either, but they put on a great show and were all excellent musicians.

Marty Stuart and the Fabulous Superlatives last night at a small venue the Reilly Arts Center in Ocala, FL.  Fantastic show of true musicianship. 

Jesse Cook at the Byham Theatre in Pittsburgh this past Wednesday. Great show!!!

Me and the wife hosted an acoustic jam last night on the back porch.  Two fiddles, Celtic Harp, a guitar and a banjo.  Fidelity was high.  Musicianship was, to use a euphemism, good natured...
