Billy Bragg writes folk-based rock songs with poetically honest lyrics, inspired by ‘70s punk rock. He laid a gauntlet both for Frank Turner's rousing small-town rhetoric and the self-mythologising everyday details in Courtney Barnett tracks. His political clarity can also be found in the outrage of Bright Eyes, while his eye for the absurd pops up in the splenetic rage of Sleaford Mods.
