No ACL webcast for weekend 1, but according to the ACL email sent out today, there will be one for Weekend 2: "We'll be live-streaming 40 Weekend Two performances on two channels at aclfestival.com, including Kings of Leon, Depeche Mode, Wilco, Phoenix, Dawes and many more! Full schedule coming next week." Fingers crossed for a Cure webcast!
Update (10/08/13): Now confirmed! The full 2 hour set will be streamed live this Saturday! Check here for the full schedule.
