To be fair to that other (non-drummer) Hal Smith, he was probably remarking about the Sunnyside, Queens Memorial concert, not the Bix Festival in Davenport, where there certainly was HOT traditional jazz, some of which was produced by the beat of drummer Hal Smith. Somehow, Andy Schumm and Josh Duffee just keep getting better, and all the bands I heard were solid.
Hot weather shouldn't keep anyone away from Davenport. The weather outside was seasonably warm, nowhere near triple digits, and the two inside venues--the Rivercenter and the Adler Theatre--were comfortably cool. Sound and lighting in the Adler were perfect, and the seats there were quite comfy, too!
