Also on Friday night, the St. Louis US Air Guitar Qualifier went off. It was sibling rivalry night in air guitar for sure, because as well as Dry Ice's sister winning Houston (and therefore bringing the two of them into direct competition at the Midwest Semi-Final in Chicago), you had Kansas City's Stack siblings, Stack Attack and Stack Hammer, descending upon an unsuspecting St. Louis, as well as Mean Melin's sister Crystal Richter (who would only wind up facing him down if they meet in the national finals, since St. Louis feeds into Chicago's semi-finals, but he'll be competing in the NYC semi-finals).
