Did anyone mention Einstürzende Neubauten ? Guess you should check their 80's stuff (even if some call it more indus than goth).
And what about Killing Joke first 2 lp and singles ?
Early Wall of Voodoo (Stan Ridgway period) should be tried too if you ain't afraid of mixing Suicide with country music !
About Bauhaus, I really loved them when I was a kid but I can't listen to them anymore...much too arty and Bowiesque to my dirty old ears...
About the intro of "Bela Lugosi's dead" picked up by The Dirtbombs in their "Kung-Fu" version, Jay Reatard did the same thing in "Blood visions" (the song).
About The Sisters of Mercy, if you ain't dead of too much laughing after listening to their "First and last and always" lp, you'd better try the first eps, especially the one with "Alice" and their cover of "1969". Those eps are also gathered in the "Some girls wander by mistake" cd. But, once again, you may laugh more than cry... which is quite a pity for a wannabe dark and romantic goth !
About the bands that deals with dark and horror themes, you can't forget the kings of Psychobilly : The Meteors !
At last, I would say better forget about all these not so great bands, who probably used to spend more time fixing their dark mascara and blood red lipstick than practicing witchcraft in spooky cemetaries under the full moon, and please check each and every stuff with Steve Pallow or Haunted George in !!!
