Browncoat songstress Marian Call is about the best there is. If you've gotta put a genre on her, I'd probably throw her in a sort of a jazz style, but much more accessible than the stuff you hear on NPR. When she first released a Quantum Mechanix commissioned album themed around Firefly and BSG, no one had heard of her outside of Anchorage. Today, she's a favorite of Wil Wheaton and the geek gods of Wootstock. Throw your support her way and get her new album, Something Fierce! What I've heard of it so far is dang good!  You can stream it online for free, purchase it through her website, or now you even have the option to purchase it on Amazon.  So, add it to your wishlist for the holidays!
