The First Midwest Bank Amphitheater is an outdoor music venue located in the southwest Chicago suburb known as Tinley Park, Illinois. The amphitheater first opened in 1990 to hoards of excited Chicago music fans as the theatre promised to be one unlike any other in the Chicago area. To this day it is still one of the largest music venues in the greater Chicago area. The First Midwest Bank Amphitheater can hold up to 28,000 guests at a time and features ample parking thanks to its suburban location. During its time as a theatre the First Midwest Bank Amphitheater has been called a number of names including the Tweeter Center Chicago, the World Music Theatre, and the New World Music Theatre. However, in 2006 the First Midwest Bancorp Inc. acquired the name in a seven year deal.
