Demitasse, a two piece acoustic group, will play at CentralTrak for a one-night performance of their debut album Blue Medicine, a side project for Erik Sanden and Joe Reyes of the San Antonio art rock band Buttercup.

Reyes is a Grammy Award-winning guitarist and multi-instrumentalist, while Sanden composes songs that NPR calls “jangly art rock for the left side of the brain.” Together in Buttercup and now in Demitasse, they sing together like brothers and are charmingly familiar with their audiences. Both Reyes and Sanden recently lost their fathers, and their debut record grew out of the chaos of caring for loved ones with long-term illnesses.
