I always like to learn what the first readily-identifiable song of a genre happens to be. According to this fascinating BBC Why Factor podcast, the first clearly-identifiable Goth song is 1979's "Bela Lugosi's Dead" by Bauhaus.
Goths amaze me. I remember once being on the floor of a casino in Las Vegas. The atmosphere was unimaginably-crass: noisy crowds laughing and farting to the clanging sounds of slot machines. Suddenly, like a ghost, a Goth appeared - an 18-year-old woman with only traces of red around the eyes to break the grim darkness of sorrowful mourning dress. She glided across the casino floor, eyes darting neither left or right but focused straight ahead, perhaps contemplating a funeral.
I should hire Goth pallbearers for my funeral.
