The Guardian’s use of FaceBook’s new live video feature in bringing us a performance of Steve Reich’s Different Trains with a film from Bill Morrison was really refreshing. Apart from individuals broadcasting lengthy snippets of their daily life which are of dubious interest, the use of live video on Facebook has been limited to the tired efforts of some media to imitate talkshows or live reportage. Because of the nature of the set-up, these attempts lack the tension and the rigour that TV can pull off and as a result cannot hold the audience’s attention. The presentation of Reich’s work, in comparison, gives us a privileged place next to the stage during the performance of a key work. The impression of being present, unless of course we cannot stomach Reich’s music or the difficult subject treated, has us captivated. At the same time, the set-up enables us to exchange impressions and ideas with those watching. Despite a lot of self-congratulatory chatter, this exchange contains some intense and meaningful moments both during the performance and the subsequent interview of the composer and filmmaker. This bringing of culture and contemporary music to Facebook in such a striking way is a really promising development.
