Today (11th September 2021) marks 20 years since the 9/11 terrorist attacks which took the lives of 2.977 people (see also this article on people who died from cancer which was directly related to the tragedy). Given this important date, I thought I would pay tribute to all those who suffered and/or died in this tragedy, as well as to all those who fought bravely to save people in the aftermath, by sharing this powerful soundtrack composed by Terence Blanchard for Spike Lee’s film 25th Hour (2002). I consider this film, based on a book by David Benioff, to be the most significant 9/11 feature film. While it does not speak of the tragedy directly, it conveys movingly the 9/11 atmosphere just after the attacks and somehow manages to show collective and individual trauma caused by the tragedy, albeit indirectly and somewhat symbolically. The film contains resonating messages on loss, grief, isolation, confusion, anxiety, missed opportunities and responsibility.
