I can't think of an album cover that has inspired me more.
My first copy of Brotherhood, and my first exposure to New Order, was via a badly dubbed tape casette. I recall the tape just had 'Brotherhood' scrawled on it, with no mention of the band. I played it to death. When I finally saw the album in a shop, I was sold.
I've always considered Peter Saville's work for New Order to be some of the most tasteful and respectful work around.
