When the Pritzker Pavilion was built members of the Petrillo family wanted it named after James Petrillo.
 There has been much debate about which concerts and festivals should remain at the Petrillo and which should be moved to the Pritzker Pavilion.
The initial plan was that the larger annual music festivals such as the Blues and Jazz Festivals and Taste of Chicago would continue to be held in Petrillo Music Shell because they are too large to be hosted at the Pavilion.
 However, smaller festivals such as the Chicago Gospel Music Festival have been hosted at the Pavilion since 2005.
There has been public opinion that some of the Blues and Jazz Festival smaller events should be moved to the better and more modern acoustics of the Pavilion.
By 2009, as the city grappled with a budget deficit, it considered realigning parts of the larger festivals with the more modern venue and made definite plans to move some of the smaller ones there.
