Their third appearance at R+L, ADTR formed in Florida in 2003 and played an impressive 200+ live shows in their first year of touring, gaining a huge fan base. They've since toured with Rise Against and Bring Me The Horizon, and released fifth album Common Courtesy after a battle with their old label Victory Records at the end of last year.

Mixing metalcore and emo, expect to hear festival favourites Homesick and If It Means A Lot To You when they make a welcome return to the Reading and Leeds stage
