Julie Davis started making solo music as Bluebook in 2005. Since then the Denver bassist and singer has led bands like Bela Karoli and Fairchildren, and collaborated with fellow Colorado artists Nathaniel Rateliff, Gregory Alan Isakov and Porlolo. This year she returned to Bluebook with her latest musical partner, singer and keyboardist Jess Parsons. Bluebook released the EP "The Astronaut's Wife" this month. Before its release, Davis and Parsons played three songs in the CPR Performance Studio and brought some unique decorations for the space. They also spoke with Alisha Sweeney about their deep musical connection and the inspiration behind their costumes and stage installations.
