I wonder if the band's songs will always take a stripped down approach, or if they'll change their sound a bit for future recordings. Most people, I've noticed, don't like it when bands don't deliver something "new" or "fresh," and remain stagnant in their songwriting/production. Although I'd be ecstatic to hear much, much more of the same, I can't help but wonder what the band would sound like if they switched things up from time to time. Ah well, I'm sure there'll be plenty of time until their next album for speculation.
All this said, my favourite 5 Fleet Foxes songs (in no order) are:
Blue Ridge Mountains
Quiet Houses
Mykonos
White Winter Hymnal (not at first, but it's a grower)
Heard Them Stirring
