This documentary really surprised me – not only because of the musical event it captured, with Billy Joel taking his band, songs and family to the Soviet Union in the Cold War year of 1987, but because of the emotions it captured as well. The evolving reactions by the crowds as Joel toured various cities behind the Iron Curtain, and his private interactions with everyday citizens – it all makes this much more than a concert documentary. It would be part of a perfect double bill with another documentary: Exporting Raymond, Phil Rosenthal’s account of trying to adapt Everybody Loves Raymond for a Russian audience. If you missed A Matter of Trust when it premiered Friday, catch the repeat tonight.
