Do you know who sings this?

I was watching pop-up video and this video came on and i like it,i watched it a few weeks{4,5or 6} ago,and now i got that song in my head not the lyrics just the beat.The lady was black and she had short hair like a guys and it was braided going up in spikes.The video was in a sepia kind of black and white color,her album cover is just her face.In the video she was wearing a black turtle neck sweater and i think the backround was a brick wall.So far the knowledge i got about her was she went to college and i think they said she sang in a cafe.

its like an indie,jazz,blues.That sort of music
Thanks
