what do you mean published media? some are on iTunes and two were released as 7-inch vinyl singles. i am not listing him here because there is a duplicate thread with that info. the original intent was a companion compilation CD. that plan seemed to fall through as not all artists responded. the double a-sides "full moon" releases stopped many moons ago. i am doubtful of a CD, but will keep "thinking positively positive thoughts." i know this link has been posted, but here is a PG interview originally describing the concept. to date, i have not seen any information on "other artists filling the slots."
