  • 4 (07:18) **John Thorn's Baseball: The Sound of Silence** - John describes his first game in 1957, emphasizing that what captivated him was the quiet of the ballpark—the crack of the bat, the thud of the mitt, the coach's yell.
  • 5 (08:53) **The First Collision: Baseball and Music in 1862** - John traces the origin of music at baseball games to the Civil War era, when the first enclosed ballpark opened with a band playing "The Star-Spangled Banner."
