It was an evening for the Grammy history books that included unexpected duets, GaGa performances, and of course, remembering M.J. Check out these photos from the 52nd Annual Grammy Awards.
Now you can truly start making your Lollapalooza plans.
Not surprisingly, the headliners are Lady Gaga, Soundgarden, Green Day, Arcade Fire, The Strokes and Phoenix.
Let the debate begin on whether this year's lineup is worthy of your dollar. Outspoken Lollapalooza-critic Jim DeRogatis called it "Chicago's musical Walmart on the Lake" and characterized the remaining lineup as an "Old Country Buffet-style smorgasbord of established indie-rock buzz bands."
The Chicago Tribune's Greg Kot says "diversity is lacking" on the bill, while Time Out Chicago calls it the "most soulful Lolla yet" with artists such as reggae legend Jimmy Cliff, Raphael Saadiq and Nigerian singer Nneka.
Discuss. Debate. And rock out.
Lollapalooza is set for August 6-8 in Grant Park.
