Simple Plan will perform at Riverdale Regional Park in Adams County on Saturday, Sept. 9. From their new millennium rise to MTV superstardom through pop-punk’s modern resurgence, Simple Plan has been an indelible part of pop culture since forming in Montreal in 1999.  

General admission concert tickets start at $40 and will go on sale at 10 a.m., Friday, March 31, at riverdaleregionalpark.org.
