Austra a couple months ago. Her album, Feel It Break, released last year. She sorta reminds me of Siouxsie; a goth feel with haunting, dark electronica. Maybe a little Kate Bush, too. I'm pretty excited, she's gonna be playing here in September and it's pretty cheap (The Independent, if you wanna come with), so that's something to look forward to. If you decide to pick up her album, make sure you hunt down the "deluxe edition" which has excellent covers of Woodstock (Joni Mitchell) and Crying (Roy Orbison) on the second disc as well as a few other b-sides.
