A Four mallet quartet about how mysterious clouds that just make you wonder what is really going on up there. My piece Mysterio, from the word mysterious, is to bring to life these mysterious clouds, with the ongoing random intros and the slight darkness of the notes paired with the moving fast notes from the marimbas and vibraphones. One day I looked up and saw these clouds and wondered what was going on. So, I randomly was bored and started making a piece about it and it just all started.
