These videos created for Al Jazeera’s The Listening Post are an interesting resource. I’ve not managed to watch them all yet. Natalie Jeffers’ (co-founder of Black Lives Matter UK) video on Stuart Hall and Alex Chow’s (student leader of the 2014 HK umbrella movement) are good (see below).
There are three more videos, on Barthes, Chomsky and Said. Check out The Listening Post website.
