Another sure sign that summer is coming, the Minnesota State Fair announced three of its grandstand concerts today, two of which feature two of the biggest rap/rock acts around, and one of which features Sunday's Oscar winner for best supporting actor. Here are the shows:

*Linkin Park with openers Thirty Seconds to Mars and AFI on Tuesday, Aug. 26. "Dallas Buyer's Club" star Jared Leto fronts the middle-slot band. Still in steady rotation at 93X and other hard-rock stations with such early-00s singles as "Crawling" and "Numb," Linkin Park skipped the Twin Cities after the release of 2012's "Living Things" album and thus could be a big draw, despite dwindling record sales. Tickets go on sale Friday at 10 a.m. for $81 (general admission and reserved seating), $71 and $51 (reserved seating).

*Kid Rock on Saturday, Aug. 23, with an opener to be announced. Detroit's urban cowboy has been coming to town just about every year, most recently with Bob Seger at Xcel Energy Center. Still, he should also be a big draw on a Saturday night at the fair. Tickets go on sale next Saturday, March 15, for $66.50 and $51.50.

*The Happy Together Tour 2014 with The Turtles featuring Flo & Eddie, Chuck Negron (Three Dog Night), Gary Lewis & The Playboys, Mark Farner (Grand Funk Railroad) and Mitch Ryder & The Detroit Wheels on Mon., Aug. 25. What's a Minnesota State Fair without an appearance by what's left of the Turtles? Tickets go on sale March 15 at noon for the happy-together price of $21.

Grandstand tickets can be purchased via mnstatefair.org, etix.com, by calling (800) 514-3849 or in person at the State Fairgrounds ticket office.
