This has a very bold and full leather profile, neither too animalic or fecal, neither too fresh and conventional, surely it has a modern blend to it which makes it really special. I don't like drawing comparisons because people might diminish one or the other subject but if you enjoy one of those deeper, heavier Electimuss fragrances like Black Caviar, Capua (I don't remember too specifically) you'll love this one. While these are very constructed, "Neandertal Dark" manages to convey a striking and decryptable smell right off the bat in the first sniff despite the long note listing. In my opinion it is a solid fragrance that has an intermediate sourness to it, the only aspect I didn't like.
To me the note listing should put more emphasis on (in decreasing order of concentration) : labdanum, violet, leather, cypress, tobacco, oud, cashmeran, tomato leaf.
