Fucking awesome album, one of my top 3 records in my collection. I liked it enough to track down the jewel case version after buying the digipak first. Their EP Siberian Church Recordings is also sick, well worth the time it took me to get ahold of it.
It has nothing to do with prog. It has to do with that fact that Tom Brady/Randy Moss nearly gave away the fact that he is not a real person but instead a manifestation of a current or past um member.
