Mooooooooooooore dubstep. Yep, we keep on throwing it your way. I've said it before, and I'll say it again: 2011 is the year of dubstep.
To be fair, this track was released in 2010, and may have ushered in the advent of folk-dubstep remixes (for those frequent visitors, you might have enjoyed this folk James Vincent McMorrow remix a week back). I find it particularly beautiful in that the dubstep layer compliments the sweet harmonies of Fleet Foxes.
