Looks to me like two lights with snoots, a hair light and a light shot up under the chin to just skim the facial profile, lots of underexposure and overdevelopment to make a very high contrast neg. Classical lighting, not done with Sofbox or Umbie.
May also be shot/transferred on Kodalith film.
If you like this style, search for an Amphoto book, Darkroom Magic by Otto Litzel. Lots of this kind of photography. High contrast, solarizations, bas relief, etc.
