She is that giddy, goofy girl from your college dorm gone viral, and she’ll bring her laid-back, personable stage show to The Basement this Friday on the heels of a Conan performance, an Entertainment Weekly feature and a professional video for “Stay Awake” that nearly matches the contagious whimsy of her star-making home videos.
