This is a remix by Gold Fields for the track "Flaws" (clearly). You may be familiar with Gold Fields already, as they got a bit of exposure taking on Passion Pit's "Take A Walk."
But who are Hunting Grounds? Formerly operating under the name Howl, "Flaws" is the second single off the Australian band's debut album In Hindsight (which we haven't actually heard much about yet. Clearly our Aussie representatives are slacking...).
If you're more curious to hear more, the full album is available now on iTunes!
