Drew & Ellie Holcomb: Rain or Shine Tour brings the married duo's roots-rich, harmony-driven sound to the Tivoli Theatre in Chattanooga. Drew and Ellie have been making music together for nearly two decades, and their first duo album, Memory Bank, became the longest-charting release at Americana radio. The Tivoli is a beautifully restored historic theater, so every note feels warm and close. Expect disarming honesty, timeless storytelling and plenty of heart.
