Power Theory proudly look back on their musical career, during which in the last 8 years 3 complete albums and 2 EP's have been created. As 2019 draws to a close, the quintet from Philadelphia will release their most expressive and ambitious album "Force of Will" so far, with some important changes within the band. Guitarist Bob Ballinger and the new guitarist Carlos Alvarez (SHADOWDANCE) unleash huge riffs and epic melodies. Power Theory creates a tightrope walk between classic and modern heavy metal American/European style and defines their own unique style with a lot of harmonic finesse. In addition, the legendary Piet Sielck (IRON SAVIOR) could be won for a guest appearance in "Spitting Fire".
