From the band's FB: "Philadelphia, PA. Here's the score. Yesterday, Ashe succumbed to an illness he's been fighting off all tour. We only knew he couldn't perform at about an hour or so before stage time. So, we're letting you know in advance that we may have have to perform instrumentally, tonight. We hope you understand. We will of course keep you updated and hopefully Ashe can perform alongside the rest of us. Thanks, TesseracT."
Darn, I love Ashe's voice. Hope he's better for the NYC show tomorrow.
