Fleet Foxes is prob my 2nd or 3rd least favorite band, First Aid Kit is horrible too.
Similar groups (other than the most obvious ones)
Local Natives
Grizzly Bear (<3 Ready, Able)
16 Horsepower - Heel on the Shovel
Agincourt (Vaguely)
Okkervil River is another terrible one, vaguely folksy but really nothing like Fleet Foxes
