Dierks Bentley is duping his fans. At his concert in West Palm, Florida last week, Bentley wore a disguise and opened his own show. Wearing an over-sized shirt, blue jeans, a cowboy hat and sunglasses, Bentley performed for two-hours with the incognito Bolo Boys Bluegrass Band. Bentley was recognized by a few fans, who took posted pictures and videos to social media. One even called the idea "genius."
