I think SexMagic is the second best fragrance I've encountered in my sniffs of House of Matriarch perfumes. It's like Blackbird's non-green cousin that smokes cigarettes...kidding...but SexMagic does smell slightly similar to Blackbird with the addition add some smokey resins & wood and removal of the seaweed/marijuana kick in BBs opening. I'll have to smell both side-by-side soon.
I thought Alpha was pretty good, if you like pine/fir fragrances. I liked it a lot more than Norne, mostly because it wears easier, yet has somewhat of the same aesthetic.
Bohemian Black was note my thing...a good enough fragrance and very interesting. However, I found it a little too sweet/floral for me at one point...not that it isn't masculine (because it is masculine leaning IMO) but strong white florals aren't really my thing.
