Arctic Monkeys, Jack White, The National, and Vampire Weekend all play different days, so if you were hoping to catch the big indie/alternative rock names and just go one or two days, that's kind of a bummer. St. Vincent the same day as Vampire Weekend is a nice touch though.
Day one has Jack White, Yeah Yeah Yeahs, and more; day two has The Gaslight Anthem (playing 'The 59 Sound'), Japandroids, Manchester Orchestra, The Menzingers, and more; day three has Eminem, N.E.R.D., and more.
Jam vets The String Cheese Incident are playing for the eighth year in a row, and Bassnectar — who headlined both weekends last year — is back too. The lineup also includes Cut Copy, !!!, Chromeo, Bonobo, Washed Out, Floating Points, Hiss Golden Messenger, Noname, Sinkane, and more.
