I found out about it 'cause I'm on a DTB email list that Sony runs, so if you're not on the mailing list, you'll have to register. You can do that on the ticketing page.
It's funny, just earlier today I was going through my DTB shows at work for something to listen to and trying to remember wen the last time I saw the band live was. It's been too long, but that will be rectified in a few months!
