The 48 date run, which includes a stop at the Frank Erwin Center on Aug. 9, comes hot on the heels of her hit two-year residency in Las Vegas at The Colosseum at Caesars Palace. Opening the show for Twain’s ROCK THIS COUNTRY Tour stop at the Erwin Center will be Grammy Award nominated singer/songwriter Gavin DeGraw.
