Johnna Katherine has 2 Polyphia concerts.

Hailing from the quiet suburbs of Plano, Texas, progressive rock outfit Polyphia are anything but mild-mannered. With a distinctly thought-out and well-orchestrated sound, the quartet pummels out blistering blast beats, and an onslaught of guitar shreds that blends, seamlessly, with melodic grooves and a humble intensity that never wears on the ear. Capitalizing on a "Standard of Excellence", the band wishes to inspire those who listen with their doctrine of uncompromised work ethic and self-motivated success.
