The American Idols Live Tour, a solid road-show attraction in previous years, is playing to many empty seats this year, with not a single sold-out performance during the first 30 of the 57 shows scheduled, USA Today reported today (Wednesday), citing figures from Billboard magazine. According to the report, 14 percent of the shows were below 60 percent capacity, with the lowest in Birmingham, AL where only 38.9 percent of the seats were filled. A lack of sufficiently compelling talent was being blamed for slow ticket sales, but at least two experts cited a hefty boost in ticket prices to an average $60.45 for the current tour. The figure is 13 percent above last year's and a whopping 35.9 percent above 2005's.
