The last notes have been played at Golden Gate Park in San Francisco, which means the 2009 Outside Lands Festival has wrapped up. Tenacious D closed out the weekend with a crowd-pleasing set of their acoustic metal epics. The Beastie Boys were originally supposed to wrap up the weekend, but they had to bow out due to Adam Yauch's cancer treatments. The choice of replacement raised a few eyebrows, including among other performers on the bill. In fact, M.I.A. (who played the set just before the D on the main stage) posted a series of tweets to her official Twitter about her disappointment with having to go on before Jack Black and Kyle Gass. "Can't believe they replaced Beasties with Tenacious D? And if I pull out they sue! So really? Tenacious D after me?" she wrote on August 22. She also noted that the only reason why she took the Outside Lands gig was because she would get to go on before the Beastie Boys. She's clearly a fan, as her set on Sunday evening featured an entire section dedicated to the absent hip-hop trio where she freestyled over the beats to "Intergalactic" and "Sabotage."
But Tenacious D were not taking the slight lightly. During their conversation with MTV News just prior to their festival-closing set, Black had some choice words for the singer. "She didn't want to open for the D," said Black. "But you know what? Sticks and stones may break my bones, but tweets will never hurt me." He obviously wasn't that put out, as the duo took the stage to raucous chants of "We Want D!" and by the time they hit the first few notes of "Kielbasa," they gave the thousands on hand one last thrill to close out a memorable weekend.
