On Wednesday, two rock superstars announced upcoming dates. Touring in support of his new album "Devils & Dust," due April 26, Bruce Springsteen will come to the Rosemont Theatre on May 11 as part of a solo acoustic tour. And celebrating the release of "Mighty Rearranger," out May 10, Robert Plant, "The Golden God," will stop at the Auditorium Theatre on July 9 with his band Strange Sensation.

No word yet on when tickets will go on sale for either concert.

Also, the Mayor's Office of Special Events has worked with sponsoring radio stations to bring several big names to the Petrillo Music Shell in Grant Park as part of the annual Taste of Chicago festival. Fugees veteran turned acclaimed solo artist Lauryn Hill kicks things off on June 24, and Latin rock giant Carlos Santana performs with openers Los Lonely Boys on July 2.

Other Taste of Chicago acts include LeAnn Rimes and Aaron Tippin (June 25), Clint Black and Julie Roberts (June 26), disco diva Donna Summer (June 28), the Gap Band and Morris Day and the Time (June 29), Lynyrd Skynyrd and Creedence Clearwater Revisited (June 30), Stevie Winwood and Dr. John (July 1) and John Hiatt and the North Mississippi All-Stars at the festival-ending concert on July 4.

Clear Channel already is selling tickets through Ticketmaster (312-559-1212) for several shows at the Tweeter Center in Tinley Park this summer, including Reba McEntire and Brad Paisley (May 21), the Dave Matthews Band (June 2), the Sounds of the Underground Tour with Lamb of God (July 8), Tom Petty and the Black Crowes (July 15) and Motley Crue (Aug. 27).

Word is expected soon on ticket sales for the annual Warped Tour, which stops at the Tweeter Center on July 23, and the heavy-metal extravaganza Ozzfest, which arrives at the same venue on July 30.

Finally, Lollapalooza -- which continues to seek city approval to take place in Grant Park on July 23-24 -- won't be the only alternative-rock festival in town this summer. The Chicago-based indie-rock Web site Pitchfork media.com has secured a city permit to host a July 16-17 festival starting at noon in Pulaski Park, located at Blackhawk and Noble on the West Side.

Called the Intonation Music Festival, and hoping to draw 10,000 adventurous music fans, it will feature two stages with 24 underground acts, including Fiery Furnaces, power-popsters the Wrens and the M's, Broken Social Scene and DJ sets.
