Collecteurs is pleased to present a series of unique records made on X-ray films featuring unreleased tracks and audio from artists and thinkers, including Massive Attack, Jónsi of Sigur Rós, Pussy Riot, Alex Somers, Noam Chomsky, Nástio Mosquito, Cyborg Neil Harbisson, and Lord Mayor of Sheffield Magid Magid. Together with this influential group of artists and thinkers, the project—titled The Library of Dangerous Thoughts—is the start of an initiative by The University of the Underground in partnership with the digital museum Collecteurs, and the Bureau of Lost Culture to raise awareness against censorship and encourage plurality of thinking.
