Not the Antidote from the Netherlands, this is the side-project band that members of Chumbawamba + The Ex started, I'm not quite which members, nor do I really know much about them, all I know is that they released 2 (I believe) great EPs.
Often considered as "anarcho-punk's best kept secret" The Sears hail from Wednesbury, Englands. Formed in January 1981, The Sears only released one LP (that I know of) on Blurrg Records in 1984 called "If Only". Give them a listen if you're into fast female fronted anarcho-punk.
What better way to start than with Omega Tribe. Formed in 1981 (originally called Deadly Game, before becoming Omega Tribe). Went on to become one of the most influential anarcho-punk bands, releasing their 1st EP (Angry Songs) on Crass Records.
