Moustache May you say?
Back in 2010, I lived across the hall from Jon Paul Douglass (http://www.jonpauldouglass.com/), the man behind the visual conceptualization of In Waves. JPD and I got together daily for the month of May that year to experiment very early on to test out some In Waves ideas. JP and I worked for well over a year before the visual-process officially even began for the lastest Trivium record.
Here is some of the fun we had on a site called Moustache May:
