I've been asked by a number of folks about the sticker above, which graces the cases of both of my guitars.
The sticker is from a web site called All Hail The Black Market, and it's run by a guy who spent years in the bicycle industry and goes by he name of Stevil. I will admit that some of what he sells is either not to my taste, or is simply inappropriate for the life I live now (as a teacher of Other Peoples' Children). But this sticker screamed at me the first time I saw it and I knew it would have to go on my guitar case.
For me, the saying is really about radical change and growth.
