From the MC5 to Underground Resistance, the industrial metropolis Detroit has always been a centre for white as well as afro-American counter cultures and revolutionary pop-culture movements. Following the film "20 to Life – The Life and Times of John Sinclair", the talk provides an opportunity to take a critical look at the Detroit underground from the heyday of the 60s and 70s up to the present. What remains from the demands, actions and independent strategies that were developed at that time? How does John Sinclair, one of the defining figures of this time, gauge the situation today – in Detroit and elsewhere? And how does David Brainard, noise-activist and member of the performance group Princess Dragonmom? Which political and emancipatory potentials does pop culture have for them today?
