Brad Paisley‘s appearance Saturday (July 10) at the AquaPalooza 2010 Signature Event near Austin, Texas, attracted more than 65,000 fans and 7,000 boats. The concert at The Reserve at Lake Travis was accessible only by boat, although some fans got closer to the stage with flotation devices. The stage included a floating 100-foot extension that allowed Paisley to walk among the fans. Attendance was approximately twice as large as last year’s estimate. The show also featured Jerrod Niemann and Lee Brice. Paisley’s H2O World Tour travels to Illinois this week with shows in Chicago and Moline.
