The Dresden Dolls gig I went to in 2006 was one of the best shows I've ever been to. I don't even love the Dolls (I do like them), but they put on a phenomenal show. The show was released on DVD too which is pretty cool, you can totally see the back of my head in one of the crowd shots
I just bought tickets to see Amanda solo with just her and the piano in October, I'm intrigued as it'll be so very different to the spectacular they put on as a band.
