here are 3 links to hear an acoustic set performed by Skin for Kerrang.
I don't know when these were recorded, but im taking a guess that it was recently.
However the bad news is, these are streaming files only, you unfortunately cannot download them, but the quality is great, so your in for a treat:
Hedonism (Just Because You Feel Good)

Just Let The Sun

Purple

I must say 'Purple' sounds hauntingly beautiful when it is played Acoustic, and im sure you guys will love it.
