Blame it on medEia — or Faustus, or any of the other challenging, nontraditional fare Spoleto packed into in a season more stuffed than usual with programming whose ability to put butts in seats was hardly guaranteed. The final box numbers are in for the 2007 festival, and it looks like Spoleto’s four-years-running record-busting streak has finally come to an end. But it’s still a pretty impressive end: Final sales for this year’s festival were $2,945,452. That’s $29,000 less than last year’s record tally — but still $413,000 above where the 2005 festival’s sales ended up. It was swell run, but it’s over. Still, I wouldn’t look for Cats! next year.
