"The Events" is a harrowing play, and unfortunately a topical one. My guess is that it was inspired by the massacres of Anders Behring Breivik, given the shooting's racial motivations. Sadly, in recent times, David Greig could have taken inspiration from any number of mass-shootings. Given the motive, it is a daring, yet confusing choice to cast a black actor in the role of the shooter. It is also just a mindbender of a play, and there are moments when more than two actors would have made the narrative easier to follow. However, Joseph Gibson is more than up to the task.
It is a cliche to call it haunting, but I think the word is apt, when it takes a day of "digestion" to write about the play. I wholeheartedly recommend "The Events". Catch it before it's all to brief run is over.
