On Sunday, take the Jazz Train, in lieu of the A Train.
A jazz trio will entertain riders on a special charter train from 1 till 3 pm Sunday. The Library stop at State and Van Buren will be the starting and end point for this special event, a part of the Chicago Jazz Festival August activities. It's a partnership between the Mayor's Office of Special Events and the Jazz Institute of Chicago.
Tickets are $15; $10 for Jazz Institute of Chicago members. The music will be piped throughout the train cars, and riders will be asked to rotate through cars so everyone can hear the music in person.
From the Web site:
The CHI-Jazz El Train will take you for a ride on the elevated tracks
of Chicago while you listen to live jazz in private chartered train
cars. Unlike normal CTA vehicles, food and drink are allowed on the
trains, and throughout the trip a CTA historian will point out historic
features and sites on our journey.
Read the Tribune's Howard Reich's nice take on the event.
