FROM THE NEWS NEST: Lollapalooza reveals lineup and more.

The time has arrived: Lollapalooza has answered our requests — all right, whiny and pretty pitiful begging — to know who the heck is playing the Chicago festival. Be prepared to fork over good money, because this is going to be one hell of a show: Arcade Fire (pictured), Lady Gaga, Phoenix, MGMT, Erykah Badu, a reunited Soundgarden and so many more will pack into the Windy City August 6 through 8.

Rihanna has decided to take on summer 2010 with a bang, and will be touring America’s stadiums and amphitheaters with Ke$ha as well as Nicki Minaj. All this girl power: we’re having flashbacks to a freakier Spice Girls. Hopefully Rihanna has the stage energy to fill a venue that large.

Speaking of tours you can also catch the pretty rad L.A.-based Princeton touring this month with Camera Obscura (April 16 at Rickshaw) and Love Is All. And on the 17th Princeton will be performing in Santa Cruz with rising stars Phoenix, who are on the Lollapalooza lineup; it all comes full circle, doesn’t it?
