Scent has such a direct connection to our more primal brains. Catch the whiff of an odor  you haven't smelled in many years, and suddenly you are transported back to that place and time as if in a dream. I remember once visiting an basement apartment and upon entering was hit with this smell that was exactly the same as my Aunt's cottage in rural Ohio.
A strong dose of mildew, old wood, decaying leaves, and the fresher air of the surrounding forest. Despite the fact I was in Brooklyn, I suddenly was overwhelmed with memories and emotions of that place and just sat and let the odor and thoughts take over for a while. It was a beautiful experience.
Just a few days ago, I came across an article that was mocking some strange perfumes... not traditional to say the least, but based more on evoking raw sex, strong emotions or scents that I feel are more tied to memory. Florals and citrus smells are pleasant, but life's events don't usually surround musk oil. Think of all the odors of the beach.... fish, brine, and seaweed.. not easy to market as perfume. But there are a few who are daring evidently.
Demeter Fragrance Library is putting out some novel ordors... a few favorites I would like to sample are
Mildew ( will this smell like my Aun't cottage?), beeswax, bonfire,  dirt, dust, funeral home, fresh hay, frozen pond, rubber, russian leather, earthworm and thundestorm... but there are a ton more....

 Yet another maker of fragrance... french of course has some unusual scent combinations.
Sécrétions Magnifiques by Etat De Libre D'Orange is the bottled essence of of coitus. Here is the company description:

Like blood, sweat, sperm, saliva, Sécrétions Magnifiques is as real as an olfactory coitus that sends one into raptures, to the pinnacle of sensual pleasure, that extraordinary and unique moment when desire triumphs over reason. Masculine tenseness frees a rush of adrenalin in a cascade of high-pitched aldehydic notes. The sensation of freshness is gripping. Then the fragrance reveals a metallic side, precise and as sharp as unappeased desire. We are on a razor-edge… skin and sweat mingle, and tastes of musk and sandalwood. The slightly salt marine effect stirs, arouses, and sets your mouth watering. Tongues and sexes find one another, pleasure explodes and all goes wild. Confusion reigns supreme. A subversive, disturbing perfume. It’s love or hate at first sight. Sensuous jousting is rarely satisfied with half-measures…In between Don Juan and the Woman who offers herself, arms are laid down…who will be the first to surrender?

But they also have some other wonderful ideas of fragrance:
Virgin and the Torero and Like this Tilda Swinton (love that actress)
