A short zine collecting an introduction to the concept by Matt Colquhoun that appeared in 'krisis journal for contemporary philosophy Issue 2, 2018: Marx from the Margins' and the unfinished introduction to the unfinished book on Acid Communism that Mark Fisher was working on before his death in 2017. "In this way ‘Acid’ is desire, as corrosive and denaturalising multiplicity, flowing through the multiplicities of communism itself to create alinguistic feedback loops; an ideological accelerator through which the new and previously unknown might be found in the politics we mistakenly think we already know, reinstantiating a politics to come." —Matt Colquhoun
