There will only be 40 EVO tickets available per show. We may reduce that amount in smaller markets.
Here's how it works:
For Paris, you need to buy a concert ticket through http://www.ticketnet.fr/
Then, you'll be able to upgrade to an EVO Experience pass by purchasing an EVO ticket through Vai.com.
For other shows, when you buy an EVO Experience ticket through Vai.com, it includes a ticket to the show in the price of EVO.
EVO Experience Premium tickets are ONLY available through Vai.com. The venues do not sell them, and the ticketing agencies do not sell them.
We'll announce the details and on-sale times for EVO shortly, but they will probably be advance tickets for all shows (meaning that we'll go on sale a week before regular tickets).
As I mentioned above, EVO Premium Experience tickets are extremely limited.
As soon as I have more info, I'll post it!
