Audiences have been flocking to Ravinia since 1904, when the A.C. Frost Company opened an amusement park that hosted a steam calliope concert of “Bill Bailey, Won’t You Please Come Home.” But it wasn’t too long before the New York Philharmonic made an appearance, and over the years, the venue has hosted everyone from George Gershwin and Leonard Bernstein to Janis Joplin and Frank Zappa.
