The Dresden Dolls

I don't know if these people are my favorite band of all time, but they're astonishingly close. Their songs are quirky and scary and simply brilliant. Lyrics are witty, music is gorgeous, everything is wonderful. Furthermore, they're catchy, sort of like California Girls but in a way that is actually pleasant, as opposed to inspiring you to tear off your ears and shove them into your larynx to stop you from humming that infernal tune.
The songs do seem to include a small bit of insanity, but it's the lovely type of insanity. As opposed to the kind of insanity inspired by California Girls, may Katy Perry have a plague upon her head.
For the record, their music is really nothing like Katy Perry. It's alt. rock.

And not to attempt to detract from the stand-alone radiance that is Amanda Palmer and Brian Vigilone, but you know what is amazing as well? Amanda Palmer happens to be married to Neil Gaiman, the author of Coraline, Neverwhere, The Graveyard Book, and much else. Every single book of his is stunning. Some of them I like more than others, naturally, but I have yet to be at all disappointed.

The next one contains Neil Gaiman's singing and many very cool costumes. It amuses me greatly.

There will be likely more to come as I listen to more of their music.
