Gothic rock music enthusiasts walk the streets between venues during the annual Wave Gotik music festival on June 11, 2011 in Leipzig, Germany. The festival began in the 1990s and has since grown into one of the biggest gatherings of Goth scene followers in Europe with around 20,000 participants. Many of those attending wear elaborate outfits and make-up for which they require hours of painstaking preparation and that also show a departure from the traditional black of the Goth scene. Punk remains a strong influence in today's Goth style as witnessed in Leipzig, but newer trends, with names like Cybergoth and Steampunk, have emerged that blend bold colors, Victorian fashion elegance and 19th and 20th century factory accessories into a look reminiscent of a mutated Venetian carnival. The five-day festival includes performances by around 200 bands. (Photo by Carsten Koall/Getty Images)
