Here is some new information for the LP version of the GREYMACHINE album via the Feral Pig blog:
white and silver inks silkscreened on black uncoated heavyweight paper jackets and inserts, with the interior jacket also printed and hand stamped LP labels. some copies will also come with an 11" x 17" promotional poster and a CD version of the audio.
This looks great and I cannot wait to see it in person. Here's to hoping they still have them available on the upcoming Isis tour.
