FF Hydra comes to my mind, or Titling Gothic. More DIN-like: Embarcadero, Geogrotesque, Skilt Gothic, Locator, Antenna. More daring: PT Vielzweck or ITC Conduit (sorry, can't link at the moment, but most should be found on MyFonts or with google)
I'm designing an invitation for a client, and I think they are looking for something very foreboding and powerful, their logomark looks like a somewhat gimmicky russian face. I set the type in DIN but they want something 'more square' - trying to find a tasteful solution, any suggestions?
thanks!
