Classical
You might not want to wear anything. I have plenty of memories of being stuck in a theatre with someone wearing Chernobyl-level amounts of “going-out” perfume. Sometimes it’s fun. Sometimes it’s like having a cell phone ringing in your ear for hours. Probably the safest bet is something pre-World-War-II. Or pretty much anything from the Chanel range. (Except Chance, Antaeus, or (egads) Blue de Chanel.)
Jazz
Try something sweet and dirty. My first thought was Dior‘s discontinued Jules (I wish I could recommend Jazz, but I just can’t). Knize Ten would be an excellent choice, regardless of gender.
Indie Rock
With so many sweaty young bodies around you, you’ll probably want something light, weird, and modern. Something like Jasmin et Cigarette or S-Ex.
Dad Rock
If there ever was a time to wear a big, strapping fougère, it’s to that Steely Dan concert. Hard to do better than Kouros, but Nicolaï’s newish Amber Oud (not really an amber, or an oud) could work great, too.
Funk/Soul
This seems like the time for an oriental. Something loud, proud, and sensual. Muscs Koublaï Khan was my first choice. Although, Fate Woman would be smashing, too. Almost anything from Amouage, and several from Serge Lutens would do.
EDM
The temptation to go for something synthetic is great. However, I think you’d be better off with something fresh but strange, like Thierry Mugler’s Cologne or Frederic Malle’s under-appreciated Outrageous by the unequaled Sofia Grojsman.
Metal
This is a tricky one. Just by chance I was wearing Yatagan at a Torché show recently, and it was bloody perfect. I’ve always thought that Secretions Magnifiques offers the right kind of rush to pair with furious sheets of noise. Then again, maybe you want to wear something to contrast, like 31 Rue Cambon or Mitsouko. In any case, probably something abstract, with a sense of uplift.
