This is music only - no video exists is what I'm told. Anyway, this is a song off their self-titled debut. It's called White Winter Hymnal. It's awesome in a mellow, My Morning Jacket-y, Built to Spill-ish, Zombies-esque sort of way.
I'd also like to add that I wrote the title "Fridays are for Fleet Foxes" thinking today was Friday. fuck.me.running. guhhhhh
