Jack White has never been fan of seeing cell phones at his concerts. At his last show at the Mayan Theatre, he had a sign outside requesting people not use their phones to take pictures during the show. It was only a request at the time but now he's making it mandatory thanks to technology from Yondr:
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.
Others have used the pouches to force audiences to hide their cell phones (Cage The Elephant did on their acoustic tour that stopped by the Soraya) and Jack is jumping on the bandwagon. So why? Here's his point of view from an interview he had on Conan.
Festival goers are in luck however - chances are that he won't have a way to force people at those performances to hide their phones.
Jack is touring in support of his new album Boarding House Reach but has not announced any Los Angeles dates yet.
