In what ended up taking the better part of the day, Bonnaroo announced it’s 2010 lineup today, including headliners The Dave Matthews Band, Kings of Leon, Weezer, and The Flaming Lips performing “Dark Side of the Moon”.

The festival used Twitter and Myspace to unveil the lineup one act at a time in five minute intervals throughout the day.  Now, all the dust has cleared, rumors have fallen by the wayside, and the full lineup has been announced.  While the top end of this list is a bit underwhelming, there are a ton of great acts in the meat of the lineup.   The festival does provide a nice mix of old and new, with performances by Guitar God Jeff Beck, John Prine, Jimmy Cliff and John Fogerty highlighting the former.  Performances by indie faves the Flaming Lips, Phoenix, The National, She and Him,The Avett Brothers, The Black Keys, Dr. Dog, and Blitzen trapper help fill in the lineup nicely.

The festival takes place 6/10 – 6/13 in Manchester TN.  Tickets are on sale at the Bonnaroo website for $234.50 + Fees (Price levels 1 and 2 are already sold out!).
