When in Iraq, this trio of brothers got held over due to dust storms (and I suspect an Air Force crew that wanted a layover). They played a free concert that went on for 3 hours of nothing but music and singing. No back up, no lightshow, no pyro, nothing but a couple guitars, harmonica, drums. They were pretty dang good playing their own and cover songs. Los Lonely Boys. They have a websight up. I tell people whenever I get a chance because they were so cool to us. Most acts would have considered our piddly little crowd unworthy of that kind of performance. They actually thanked us.
