Backbone is trombonist Mariel Bildsten's debut album as a bandleader. It features her interpretations of jazz standards and melodies. Her lyrical, swinging style and exuberant arrangements are an ode to New York City, a place that has provided inspiration, challenges, and joy. Backbone showcases Bildsten's dynamic tone and phrasing on trombone, and features the masterful interactions and artistry of Stacy Dillard on tenor and soprano saxophone, Sean Mason on piano, Ben Wolfe on bass, and Evan Sherman on drums, plus a guest appearance by percussionist Keisel Jimenez.
