I am pretty much in agreement with the Amazon reviewer on this one. In its over-all blandness, 'Four-Calendar Cafe' veered dangerously close to sinking into the deep waters of the MOR-sea and drowning; and whilst 'Milk & Kisses' is, as another reviewer commented, distinct from earlier efforts (in that it is it no mere rehash of past glories), it is truly a return to form. The loud guitars swirl and soar, as do Fraser's unrestrained and other-worldly vocals (yep, a cliche, I know, but her voice is unique and is show-cased in fine form here); the polite trilling, tame lullabies and mainstream pretensions which plagued 'Four-Calendar' are definitely eschewed in favour of heavy-reverb and multi-track heaven!
Naturally, there are one or two vaguely dodgy moments - e.g. the cheesy radio-friendly guitar on 'Calfskin Smack' has me in mind of Phil Collins or Celine Dion (?!) for some reason (despite this it still manages to sound okay) - but there are plentiful gems to make up for this. The jewel in the crown is undoubtedly 'Serpentskirt', a moody and beautiful affair, goose-pimple-inducing in the way only a Cocteau's song can be - definitely one of their all-time best.
Oh and yes, "Treasure Hiding" is VERY similar to "Pur", although to me that can only be a good thing as the latter was my favourite track on "Four-Calendar". Wonder why ...? :)
