This marimba duet is based off of a classical superhero vs super villain fight. "Calamity" is a song meant to portray the sheer destruction of the battle and the meaning of the word, an event often causing great damage or distress. This song, the counterpart to another marimba duet I created called "Godsend", is a fast and dynamic duet that is challenging, but overall a pleasure to listen to. Comments and feedback are greatly appreciated. Enjoy, and, as always, "Represent your shadow"!
