Some of the Bumbershoot lineup has been
posted on their site. Also,
a Seattle Times article about it.
This year's music acts include:
The Shins, Wu-Tang Clan, Panic! At The Disco, Crowded House, Lupe Fiasco, Steve Earle, DeVotchKa, Devendra Banhart, Gogol Bordello, Kill Hannah, Norma Jean, Plain White T's, The Gourds, Lyrics Born, Roky Erickson & The Explosives, The Holmes Brothers, The Avett Brothers, Yungchen Lhamo, Allison Moorer, Magnolia Electric Company, The Aggrolites and many, many more to be announced!
No one that I'm like "OMG Yes!!1" over but I'll probably try to start listening through these folks on Rhapsody as there are likely some hidden gems that I haven't heard yet. That said it'd be cool to see The Shins and Panic! At The Disco despite the fact that they're use of an exclamation point in the middle of their name rather annoying.
