Judas Priest found the one open date in September!
They have just announced that they have rescheduled their 50 Heavy Metal Years tour and have added a bunch of new dates, including a stop at the Rosemont Theatre in Rosemont on September 20th (my birthday ;)).
Tickets for all of the shows on this tour go on sale Friday, June 11th at 10am local time. There is a pre-sale on Thursday. You can get tickets HERE!
