Just to share two of my favorite bands, Diorama and Diary of Dreams. They are both darkwave/gothic, with lots of electronic stuff. If you like Rammstein, you will certainly love them.
Not to mention that Diary of Dreams' leader is the most good looking guy on stage that I know:-) Check him out in this vid of The Curse (You Tube).
1. The girls
2. Someone dies
3. Champagne for all
4. Last Minute
5. Leaving Hollywood
Diary of Dreams:
1. The curse
2. Traumtanzer (my personal favorite of all times)
Yeah, I thought you might know this one:-) Diorama is in some way a child of Diary of Dreams: it was discovered by Adrian Hates, then sponsored and they are often on tour together (that's how I got to see both on stage).
