This is the email I got from Customer Support at LiveNation.com.
Warning: It may do you no good. I couldn't even get to the page to enter my code from my Nostradamus CD.
Individuals that purchase the new Judas Priest special deluxe box set – NOSTRADAMUS, will receive a special voucher included in the CDs that they can redeem for one free lawn ticket to a participating Metal Masters show of their choice. If you have this voucher, please visit www.livenation.com and type “Judas Priest” where it says “search artists and venues.”
Next, click on the "buy tickets" link for the location where you would like to see the Judas Priest event. You may be asked to register for the Live Nation Tickets Club at this point. Simply follow the system prompts to register. An e-mail will then be sent to you. You will need this e-mail to verify your registration. If you have not received this email after trying to register please respond with your first and last name, e-mail address, state of residence, and zip code so that we can register for you.
Once the main sales page comes up, you will need to select the drop down box next to where it says "Metal Masters" and select "1" as the ticket quantity to access the promotion. You should enter the passcode from your voucher on the final page of the sale where it will ask for your "passcode, member code or coupon code." Please contact us if we can be of further assistance.
