Using a Piezo to trigger lights?

Hey all. What I am trying to construct is some kind of circuit that will trigger an LED when a piezo is tapped. The reason I would like to create this apparatus is to trigger lights using acoustic drums for my band's live show. I would like a light to go off every time a drum is hit and I figured that using a piezo would be the best way to do this. Any help that anyone could offer in this would be greatly appreciated. Thanks again.

P.S.

I found this diagram for a piezo switch but I am unsure as how i could use this or even how to make it in the first place. I am very new to electronics.
