Killswitch Engage has been at the forefront of heavy metal for over two decades and doesn’t seem to be going away. Having started their reign of terror after the demise of two highly respected bands, Killswitch has taken their former remains and turned old flesh into a zombified behemoth of metal magnitude and aggression. They are the metal band’s metal band and have set the standard for all up-and-coming bands in the metal scene. Touring with August Burns Red, their appearance at Silver Spring’s The Fillmore is destined for years of storytelling.
