The Grand Ole Opry is a weekly country music concert show in Nashville, Tennessee, which began as a radio barn dance on November 28, 1925, by George D. Hay and has since become one of the genre's most enduring and revered stages. Each show consists of multiple guest artists as well as Opry members, who are selected by Opry management based on several factors including critical and commercial success, respect for the history of country music and commitment to appearing on the program. Publicly, once a new member is chosen, an existing member will ask the new member to join the Opry live on-air during the broadcast, usually when the new member is performing as a guest. Being invited to become a member of the Grand Ole Opry is considered one of country music's crowning achievements.
