According to singer David Galloway, the name of the band was inspired by Metallica and the Periodic Table of the Elements. "I can remember sitting in a physics class when I was in Ninth Grade, scribbling song lyrics in a notebook and trying to think up a good name for the band. I also remembered that Metallica supposedly got their name from the periodic table, so as I was sitting in that class I checked out what the heaviest metal on that table was - it turned out to be mercury, which is the 80th element on the periodic charts. That's how we became Element Eighty."
