Here is the article from the Chicago Tribune:
"Eminem, Muse and Foo Fighters will be among the headliners for Lollapalooza when it returns Aug. 5-7 to Grant Park.
Reliable industry sources confirmed the bookings Tuesday. Lollapalooza promoters C3 Presents had no comment, but the Eminem booking is a coup. The hip-hop artist is expected to win his first album-of-the-year prize at next Sunday’s Grammy Awards for his latest album, “Recovery,” the best-selling album of 2010.
The Foo Fighters — fronted by former Nirvana drummer Dave Grohl — are returning with their seventh studio album in April, the band’s first set of new material in nearly four years. Muse will be playing a few festival shows while readying its next album this summer; the U.K. band scored its first major U.S. hit with its 2009 release, “The Resistance.”
Also expected to play Lollapalooza, according to several industry sources: Best Coast, Girl Talk, Crystal Castles and Lykke Li. At least three more headliners will join Eminem, Muse and Foo Fighters.
The complete Lollapalooza lineup is expected to be officially released in April.
