Antisect are a punk rock band based in London, England. Their roots are in hardcore/anarcho punk and metal.
Formed in Daventry in 1982, their debut album, In Darkness There Is No Choice, was released in 1983. 1985's follow-up EP Out from the Void has often been cited as a game changer amongst their genre for fusing a raw punk rock style with elements of metal.
Antisect are a significant band in the timeline of hardcore punk music, said to have been a major influence upon "black-clad, politically charged punks over the last 30 years".
The band address issues including animal rights and social justice, communicating their ideas to a largely punk rock audience, and were among the instigators of the squat venue scene in the mid to late 1980s. During this time, members lived the lifestyle of being either on the road or part of the vibrant London squat scene of the time. They toured extensively both in the UK and Europe and though originally splitting up in 1987, the band reformed in May 2011.
