As both a world-class performer and an advocate for her instrument, Sarah Willis is an inspiration to a generation of horn players, so I was somewhat star-struck to talk to her for this week's episode. Despite the unceasing travel difficulties and upheaval of the past two years, Sarah has been continuing to spend time in Cuba working with Cuban instrumentalists and composers. The fruits of this can be heard on her two *Mozart y Mambo* albums from July 2020 and September 2022, where she sets Mozart's magnificent horn concertos alongside traditional and contemporary Cuban dances. We dig into what makes this music tick, and how a cross-cultural collaboration can combine faithfulness to its ingredients with a knowing and sometimes irreverent angle on the canon.
