Live music fans must be drooling over the news today, as festivals large and small have been announcing their line-ups. But the best reveal of all will likely come from Bonnaroo, the Tennessee arts and music festival that kicks off June 13 and lasts for three days. 

Never one to shy away from web theatrics, the festival tapped Weird Al Yankovich of "Eat It" fame to announce the line-up on YouTube. As part of B.L.A.M. (Bonnaroo Live Lineup Announcement Megathon), he'll stream an hour of "classic Bonnaroo concert moments," then start taking calls via phone and Google+ hangout to reveal the acts, along with some band news. The number to dial is 646-918-8070. 

From there, fans will be treated to a one-hour long concert by Portugal. The Man starting at 2.
