Premier Progressive & Power Metal Music Festival for North America. Through his company, HoS Productions, Glenn Harveston is the music promoter and founder for ProgPower USA - the premiere annual festival here in North America dedicated to progressive & power metal. 2015 will be the festival's 16th year. ProgPower USA is unlike any other music festival in the world as the focus is on quality over quantity. The audience capacity is intentionally kept at 1,100 in a first class indoor venue – Center Stage Atlanta. Each year, the roster consists of 12 bands from abroad with 6 performing each night. The festival gives bands that have never performed in the States a chance to test the waters so to speak, and it also allows them to interact with fans more than ever.
