Alicia Keys issues no cellphones policy at her shows. Many people at show use smartphones to photograph performers and annoys other people around them
Adele recently embarrassed a member of her audience by calling her onstage for blocking the view of others with her phone. So Alicia opts no cellphone policy on her shows.
Show goers can take their telephones to her shows, but after getting inside they will have to place their phones in a Yondr case. As indicated by Today, these cases bolt your telephone and can be opened by tapping the case on a metal circle found in the concert’s lobby , thus ensuring that guests excuse themselves if they need to use their phones.
Apart from Alicia Keys, comedians Dave Chappelle and Louis C.K. will also use Yondr cases at their shows, reported refinery29.com. – CINEWS
