Fans in Delaware may be disappointed, but The Band Perry says the safety of their concertgoers is "top priority."
The country group was forced to reschedule Sunday's show at the last minute after two men allegedly made "alarming statements" to employees at the Americana Bayside Welcome Center.
"Due to heightened security concerns, and for the safety of our fans, the show has been rescheduled for August 17," The Band Perry tweeted. "While we are sad we don't get to see you tonight, we love you and consider your wellbeing and security our top priority."

The family band -- which consists of singer Kimberly Perry, bassist Reid Perry, and mandolin/drums/accordion player Neil Perry -- concluded by saying, "We'll see you soon."
Meanwhile, Delaware State Police tell ET in a statement that Dzmitry N. Papou, 35, turned himself in on Monday night and was charged with one felony count of terroristic threatening. Papou was released on $20,000 bail.
A second man allegedly involved in the threats "has been identified," police say, but not arrested.
The scary incident comes nearly one month after singer Christina Grimmie was shot dead after her concert in Orlando, Florida. The YouTuber-turned-The Voice alum was recently remembered at VidCon, and ET spoke with her fellow creators about the upped security.
