Folk Festival director's trends theses days are to discount traditional music as outdated. Your situation in Philadelphia is not unique. Just the name "Old Time" probably turns them off as a passe genre. How about traditional ballad singers? Do they hire them? How many not so famous older musicians do they hire in compared to not so famous younger musicians? Mariposa up here used to be a diverse festival. If you check their lineup at their website from last year you will hardly find one traditional act. It's shameful. The very definition of roots/folk music has morphed into Lord knows what. The acts they get are really good, but they are leaving out so many trad artists from the rosters that the young audience isn't even getting exposed to the music anymore.
