Amazon US has samples
up on the full I.E.D. deluxe album with the extra tracks.
Can't buy Shifting yet on iTunes or Amazon on their US sites that I could find but there's always the UK site where it seems to be available
but with the typo on the album name. "Stifing Through The Lens"
Looks like Amazon has US availability of Shifting Through the Lens at 08-June-2010. I.E.D. has availability on 22-June-2010 for both US and UK. I don't see the deluxe listed on the UK site yet.
The "Stifing Through The Lens" album is also on iTunes in the UK.
Edit: Euros are cheaper
if you are in the US. :-)
