I recently discovered a pretty interesting synth rock band called "The Birthday Massacre" and really love most of the stuff which is on Hide And Seek and Superstition.
The thing which impressed me is mainly the synth rock which has a pretty melodic structure, it's hearable in songs like "Alibis" (I think this is my favorite song by them), one of the older songs called "Shallow Grave" or "Leaving Tonight". Basically I don't really like the stuff before Hide And Seek, apart from the more upbeat songs. I would recommend to check out some of their newer stuff before posting here. Do you know any bands simliar to them? I'm really blown away by their music and now I'm looking for similiar bands ;)
