On Friday and Saturday Fountain Square keeps the good vibes from MidPoint and this summer's MidPoint Indie Summer concert series going with a new incarnation of the "Popopolis" event, which was founded in the late '90s as a way to bring the best in Power Pop and other versions of melodic Pop/Rock to Greater Cincinnati. Friday is "reunion night," featuring sets from some of the festival's original performers, while Saturday has performances by Bad Veins, Wussy, The Seedy Seeds and other current acts.
