The blues just doesn't work when it's too gussied up, surrounded by corporate banners and beer tents where you have to wear wristbands proving you're older than 21. The blues favors down-to-earth venues. That's why the music sounds so good at the Kansas City, Kansas, Street Blues Festival every year at the end of June. The parking is easy, the admission is free (though donations are accepted) and, on the festival's single stage, the sweet bands start on time. It's a true street festival -- unassuming, honest, real -- and it reminds us what Kansas City is really about.
