All this week we get additions to the essential Georgia Playlist from musicians playing at Bragg Jam in Macon this weekend, July 28-29. The series is produced by GPB’s Trevor Young. Today’s picks come from Vanessa Briscoe Hay, former frontwoman for the legendary Athens band Pylon. She’s now singing with the Pylon Reenactment Society, who perform at Bragg Jam on Saturday at Fresh Produce Records at 9:30p.m. She brings us music from The Brains and the Classics IV.
