I just stumbled across this amazing band over at the Bandcamp Staff picks page.  This San Francisco based blues/jazz five-piece goes by the name Con Brio.  Not only are their instrumentals stunning, but lead singer Xandra Corpora's vocals are some of the best I've heard in a while.  What's even more amazing about Con Brio is they just as good, if not better live.  I present to you "Not At All", both studio and live versions, see for yourself.
