Barrett Wilbert Weed's Dear Diary cancelled

Received an email from TodayTix that Barrett Wilbert Weed's Dear Diary concert at the Palladium scheduled for the 1st of September has been cancelled. All tickets will be fully refunded. A genuine shame, she has a pretty unique voice and I was really looking forward to the show. Anyone know why? I'd hate to think it had anything to do with ticket sales.
