Well I am a graphic designer by occupation and I'd like to say that Peter Saville's designs have always infuriated me. Simply cos when they're good, they're very good and when they're bad, they're utter cack.
I've noticed his quality control slipping of late ever since 1992 to be honest with you all here... The stuff he did for Get Ready is moribund in the extreme. Why this dated obsession with the colour white? Doesn't he know that when you have WHITE packaging it very easily goes grimy or off colour? Ditto the FACTORY BOX CASSETTE packaging that happened in the mid 80's .... Guess who picked the short straw for the WHITE boxes? Yup. New Order. Go to any collectors fair now and pick up these artefacts if you're lucky enough to see them - chances are they're grimy as fuck. Not nice. Especially when I like my stuff pristine and new anyway.
So, Saville - some of his classic sleeves are stuff he did with the very much underrated OMD in their earlier hipper phase:
Like the blue cut-out "waffle/grid" sleeve design for their first eponymous album.
Then the one he did for "Architecture and Morality"
Then the one he did for the 12" single "Maid Of Orleans" (very very striking)
Then the one he did for their "Dazzle Ships" album
(still highly rated in those "Best LP covers of all time" lists believe it or not!)
The only New Order/Joy Division ones I like are actually
Closer
Atmosphere
Love Will Tear Us Apart
Ceremony 7"
Blue Monday - first issue die-cut floppy disk 12"
PC&L
Low Life
Technique CD Booklet
Fine Time - original 12"
Round & Remix 12"
World In Motion - original 12" (the concept was clever, the record, cheesy)
Regret 12"
and that's it!
The covers for BOTH compilations are CRAP - IMHO
Substance
and The Best / Rest Of.
Too much white for my liking. With crap nonsensical splodges of colour as a poor excuse for something more substantial and meaningful...
Shellshock is also abysmal too.
Can't make up my mind about both editions of True Faith (1987 and 1994) however, and 1963 was bit kindergarten wasn't it?
Blue Monday 1995 was like the Testcard thing on TV - probably that was the intention. So. Naff.
I think his best work is long past him to tell you the truth.
He was a design icon of the 80s. And it shows.

Besides, MARK FARROW is the most original and creative album packaging and concept designer of the time now - look at the sterling work he's done for bands like Spiritualized, Manic Street Preachers, Pet Shop Boys, etc...
He appears to have stolen Saville's thunder - not to mention his sense of creative nous.
