I saw a tweet about Julian House giving a talk about his artwork and found this:Primal Scream - Xtrmntr (Creation)
“This sleeve has been seen an awful lot. People still come to us about it. I think it really had an impact when it came out because there wasn’t much collage work about, or sleeves that had a similar feel. The removal of vowels came out of a conversation with another designer here at Intro.
I was thinking about how barcode stickers in record shops often abbreviate titles - it can often have a militaristic feel, and this was in keeping with the concept for the album. The images come from things the band were referencing in their lyrics. It became a blend of Pop Art images, CNN footage and a PlayStation game. I worked on this in a rather haphazard way: doing rough, primitive cuts in Quark Express, then pasting them together and gradually removing the detritus. I think it looks like a sort of ‘glitch in the program’, a computer virus. The cover has a strong concept behind it and this was expanded when I worked on the inner booklet and accompanying video.”
Did some digging and found this site, with some great commentary about some of his work. http://www.intro-uk.com/category/creative/julian-house/
I haven't watched the "Kill All Hippies" video for ages and it's great, especially when you read his comment about The London Knights:http://www.intro-uk.com/work/primal-scream-kill-all-hippies/
There's some other interesting stuff on the site about the campaigns for "Evil Heat" and "Beautiful Future" as well as Can, Kraftwerk, Oasis etc.
