I don't know too much about them, so I wiki'd them. It was odd to see that it was leaked today that they are breaking up. I think it is the first time that I read news on Wikipedia.

"On August 26, 2009, it was announced by people close to band that the duo would go their separate ways: Ethan to a new group with friend Joaquin Klipschatz called Rayon Shuffle, and Alice Glass will tour solo under the band name Looking Glass. Both will retain elements of their signature 8-bit Electroclash style, while the latter will take on a distinctively erotic tone combining hard synth melodies and the erotic imagery of featured artists from the avant-garde. It is presupposed that the duo may reform at a later date, though inferred to be under another name."

I did a stage dive at one of their Toronto shows last fall. It was a fun show... but short... like their career I guess.

All in all I wont miss seeing their ongoing dramas in the news, (if the rumor is true).
