Despite being in their mid twenties, artist and musicians Anna Roberts-Gevalt and Elizabeth LaPrelle have pursued more traditional avenues of folk singing. The duo will be performing ballads and old time tunes at the Creative Alliance in Baltimore's Highland Town neighborhood on Saturday evening. They also make crankies, a scrolling panorama popularized in the mid 1800s. Their crankies along with panoramas made by other Baltimore artists will accompany their musical performance at Creative Alliance. Roberts-Gevalt and LaPrelle join Tom Hall in studio.
