Rock n' America is scheduled for July 23-25 in Oklahoma City, Oklahoma. Three-day passes and VIP tickets are still available. There's also an official hotel package.
The last time I counted, around 27 bands had been announced for the festival including RATT, the Scorpions, Cinderella and Twisted Sister. The festival website promises 30 bands, so I'd assume the bill is nearly complete...as it should be. After all, the event is next month! (Where does the time go?!)
I think Dirty Penny is a great addition - they bring in the younger element of Glam to the event. There will be multiple stages and right now, no band splits have been announced.
Here's a performance and interview I found online featuring Dirty Penny.
