I've been debating going to Europe for some time, and Primavera may seal the deal. If not, I'll be going to Sasquatch.
But really, in my mind, there is no comparison between the two. Sasquatch has some cool bands playing, notably TV On The Radio, Bon Iver, Explosions In The Sky, M83, Sun Kil Moon, The Wrens, St. Vincent, and King Khan & The Shrines. And they could possibly add some other cool acts.
But Primavera's lineup is amazing. Andrew Bird, Aphex Twin, Black Lips, Fucked Up, Gang Gang Dance, Ghostface, Lightning Bolt, Magik Markers, Magnolia Electric Co., My Bloody Valentine, Oneida, Phoenix, Shearwater, Shellac, Sonic Youth, Spiritualized, Sunn 0))), The Jesus Lizard, The New Year, The Vaselines, Women, Yo La Tengo.
I mean, the fucking Jesus Lizard. Anyone who would choose Sasquatch over this is crazy.
