This is Montagne's version of Ex Nihilo Blue Talisman. I have not had the OG and this is just a first experience, no judgement until I give this some shelf time, but so far it is solid.
This opens up sweet, pear and citrus stand out, underpinned by musk, soft white floral, and a very subtle warm wood.
I will say this, at $40ish this is worth it.
LOL - just noticed i posted a pic of the wrong bottle
