Jack White has banned cellphones from his upcoming tour:

We think you’ll enjoy looking up from your gadgets for a little while and experience music and our shared love of it in person.

Upon arrival at the venue, all phones and other photo or video-capturing gizmos will be secured in a Yondr pouch that will be unlocked at the end of the show. You keep your pouch-secured phone on you during the show and, if needed, can unlock your phone at any time in a designated Yondr Phone Zone located in the lobby or concourse.
