William Beckmann: Las Posadas Tour is a concert on the Las Posadas Tour, bringing the singer to the Majestic Theatre in San Antonio. The Majestic is a historic, ornate theater downtown, the kind of room where every note carries and the whole place feels like a special night out. This listing is for a country-music show, and the source describes the concert series as a celebration of the genre's timeless anthems, ballads and boot-stompers.
