On Sunday, March 13, Holly Macve played her first show in the United States. Two nights later, behind the bustling Austin event space Palm Door on Sabine, the 20-year-old songwriter from County Galway in Ireland sang us a lullaby. Her song "Sycamore Tree" ponders the future while longing for the past: "One day when I'm old with my past behind me / I want to lay down in the shade of the same old sycamore tree," she sings. With the sound of a restaurant fan wheeling in the background, she drove us gently through the humid night toward whatever big things may await her.
