This guy has performed at a lot of different Porchfests. He doesn't likely live at all of those houses, which makes me think about what exactly qualifies someone to perform at one. I guess the resident just has to be willing to invite you in, vampire-style?
I don't have a problem with this, but it is different from the way I thought it worked. I thought it was just whoever lived there playing in front of their dwelling, thereby giving you a sense of the artistic sensibility of the person living there.
