“Dumpster diving”, in the context of art, suggests that valuable things can be found anywhere, also in the garbage of others. I came across the expression in the chapter “No guilty pleasures” in Austin Kleon’s book Show Your Work (2014). As Kleon mentions, we all love some things that other people think are garbage.
I’d like to try out the idea that looking for art in “garbage”, those things we don’t really like to admit we experience as pleasurable, might even make us more interesting and independent as artists. There’s no good reason to define specific experiences as “guilty pleasures”, and therefore exclude them as not suitable sources of influence.
