It’s a banner week in Athens for fans of influential indie singer-songwriters, as Omaha, NE fixture Simon Joyner will play the Caledonia one night after Malkmus’ stop at the Georgia Theatre. Joyner, often cited as a forefather of the heart-on-sleeve Omaha scene that spawned artists like Bright Eyes and Cursive, has released nearly two dozen collections that have alternated between lovely and lethargic (2001’s Hotel Lives) and dense and challenging (2012’s Ghosts). His latest, Grass, Branch & Bone, released in 2015, was a stripped-down record that found him paring his music down to its aching essentials. He plays Athens with his band and local support from Little Gold, Immaterial Possession and Small Science.
