Radiohead is main Lollapalooza act

CHICAGO -- Radiohead and Nine Inch Nails are set to headline the Lollapalooza festival in Chicago in August, industry sources said.

Promoters haven't officially announced the lineup, but sources told the Chicago Tribune Radiohead is confirmed as the festival headliner.

The band reportedly said they thoroughly enjoyed performing at an outdoor concert at Chicago's Hutchinson Field near Grant Park in 2001, where the Lollapalooza is being staged this year.

Nine Inch Nails will perform for the first time in Chicago in years, after the release of the band's 2007 album, "Year Zero."

Another leading performer and approximately 100 other artists are to be announced in April for the Aug. 1-3 festival, the Tribune said.
