During the winter of 2016, Houston native Kat Edmonson fell ill. Unable to kick a bad cold for weeks, she burrowed into her Brooklyn apartment, flipped her television to theTurner Classic Movies channel — and began to write. The end result? Her just-released fourth album, Old-Fashioned Gal, a bouncy, jazzy record that channels the energy of a MGM musical. In fact, Edmonson says that as she wrote the 11 songs, she envisioned film scenes that corresponded with each — eventually conceptualizing an entire movie. She performs May 21 at Heights Theater.
