I received this today along with the oud fragrance from Kilian and both of them, of course in my initial day getting to know them, remind me of two Bath and Body Works products. Now, just wait...
So, Back to Black reminds me quite a bit of B&BW Sensual Amber products (I haven't tried the EdT of Sensual Amber but the general scent profile of the fragrance used to scent the soaps and creams is quite the same, I mean, I've reapplied Back to Black three times and sometimes I think "WOW... that's a dead ringer!)... almost powdery sweet ambery (honey in B to B's case) and I mention this just so that people will have a general idea of the fragrance. Of course Back to Black is richer, and the sweet powdery sensation is really interesting.
Pure Oud reminds me very much, once the fragrance comes into focus about a half hour in, of a candle/oil available at B&BW which I own called Firewood. I think it's by the Slatkin Company. At any rate, so that you might get the general idea again of the fragrance from something more accessible, I relate it quite a bit to the sweet, smokey woodiness of "Firewood". It's uncanny really.
Both of these Kilian fragrances are interesting, good even, but honestly, I was surprised. I find Back to Black so intensely reminiscent of Sensual Amber that I'm almost negatively taken aback. I'm curious to see how my opinion either intensifies or changes on getting to know this more.
So you're probably thinking, "well that's awfully convenient and strange that these BOTH remind him of something from B&BW... what an idiot" and I would probably think the same reading this, but... I just can't help the fact that my brain made these associations instantly to products which I've had in my home for long periods of time and gotten to know quite well. Anyway, I just thought I'd try to help by making some more easily accessible scent associations because based on the notes of both, I absolutely would never have guessed the fragrances that came out of the vials I received today. I'll report more when I get to know these better.
