It was anything but a conventional grand entrance for Rascal Flatts on Wednesday as the band kicked off its nearly three-week Las Vegas stay an event unconventional in itself, considering the group is undertaking the first ever country residency to hit The Joint at The Hard Rock Hotel and Casino. As part of the residency, dubbed “Rascal Flatts Vegas Riot!,” the band is slated to play a total of nine shows through March 14, opened each night “The Voice” season 7 winner Craig Wayne Boyd.
