The Pepsi Center is a time machine this summer. Either that, or no one there knows what year it is.

Aerosmith will take the stage on Aug. 19, right in the middle of the band's two-month summer tour. That's in addition to Kiss, Motley Crue, Def Leppard, Journey and Cher.

Tickets for Steven Tyler and Co. go on sale at 10 a.m. on April 14 and cost $39.50-$149.50.
