I think Sean Smith has his references wrong when he says that "Dungen opening for Fleet Foxes is like Slayer opening for Yanni". He might be confusing Dungen, the psyche/folk band from Sweden http://en.wikipedia.org/wiki/Dungen , with Dungeon the heavy metal band from Australia, http://www.dungeon.cd/ . Robin from Fleet Foxes is a huge fan of the Swedish band and he arranged the tour dates. He wouldn't want fans to miss seeing Dungen and Smith equating them to Slayer might mislead fans. Just sayin...
