London Grammar's Metal & Dust EP is now available in the US iTunes store and, while it does not feature "Darling Are You Gonna Leave Me", it does include "Hey Now" (and the remix), "Wasting My Young Years", and, my favorite, "Metal & Dust".
Go get the EP now because it's awesome, the band is kind of amazing and you should support them, and because you don't really have a reason not to get the EP now (it's in your iTunes store for only $5).
