Grafton Tanner has worn many hats in Athens music since moving here for college in 2009; he’s played drums for multiple projects over the years and, more recently, created an avant-garde solo project, Superpuppet. Tanner has also written a fair bit about music in that time, too, for Paste and recently defunct blog The Blue Indian. The Macon native is set to release his first piece of long-form writing, a series of essays on the haunting aspects of media and the electronic subgenre vaporwave, titled Babbling Corpse: Vaporwave and the Commodification of Ghosts. Help him celebrate at Avid Bookshop this Friday at 6:30 p.m., before AthFest festivities kick into high gear.
