Uzee and I saw Koko Taylor in Tucson in the fall of 1991. We walked there from Uzee's house to the club called The Rock because we didn't have a car and along the way we saw an enormous shooting star flash across the night sky. It felt like an omen. Then we heard Koko sing and it was like nothing I'd ever heard before. She had a great backing band too, including a very cute & spunky keyboard player who shook hands with us after the show. I think we were too in awe of Koko to approach her, or maybe she was mobbed by the crowd, I don't remember.
If you never heard her (or even if you have), check out this clip. It's two songs and the first is good-timey kind of blues, but jump ahead to the 3:30 mark or so and prepare to shiver.
