It can be the philosophical exchange between thinkers as they drink together, the fleeting moment a skirl of lark wings sweeps across the countryside, the wordless love letter Mahler wrote to his wife, and the lifelong practice of learning to embrace ourselves. Esther Yoo’s new album, Love Symposium, is an intimate meditation on love—and her violin becomes the most sincere of narrators.
