Looks like the summer radio festival season will come to a hell-razing close of sorts, as Rammstein, Creed, Monster Magnet and Stabbing Westward are among the artists that have signed on for the third annual Rockstock concert, slated for September 12 at Chicago's New World Music Theater.

Sponsored by local radio station WRCX and Mountain Dew, the show will also include sets by the Black Crowes, Anthrax, Local H, Candlebox, ex-Queen guitarist Brian May and former Living Color frontman Corey Glover, and more artists are expected to be named in the next few weeks. A portion of the concert's proceeds will be donated to the "Chicago Tribune" Charities, which helps aid and fund charities in the Chicago area.

Tickets for Rockstock '98, which will feature some 20 bands spread across three stages, will go on sale this Saturday, and will be available at all Ticketmaster locations.
