This year's Bonnaroo takes place June 11-14 in Manchester, Tennessee. The festival is currently announcing its lineup through an odd process, in which fans call 1-844-ROO-2015 to learn the name of one artist on the bill and subsequently share it on social media with the hashtag #bonnaroo. A feed at Bonnaroo's website is collecting all of the announcements—watch the lineup announcement video live below. We'll update here as the lineup is revealed.
