Iron Maiden, Bullet For My Valentine & The Raven Age bring a heavy metal bill to Dos Equis Pavilion in Dallas for an evening of big riffs and bigger energy. Iron Maiden is a legendary British heavy metal band, and Bullet For My Valentine brings hard-hitting modern metal to the lineup. Dos Equis Pavilion is a large outdoor amphitheater, so you can settle in under the open Texas sky and feel the crowd roar.
