Cousins Richard Bevan and Joshu Doherty. Based in East London & Glasgow, respectively.
Their debut release in 2000 was a series of handmade CDs simply called "Posthuman" (though better known by the colour of the card inserts - grey, black, blue and brown). The duo then went on to host a number of parties in an abandoned underground train station in London between 2001 and 2004, and founded their own label Seed Records (2) with which they released 3 albums and several other releases of their own and other artists' material. They also were the first act on Manchester based imprint Skam's SMAK sublabel.
Doherty left Seed Records to help relaunch UK techno imprint B12 Records in 2006, and started a new label Balkan Vinyl in 2010.
In 2007, Doherty founded acid-focused clubnight "I Love Acid" along with Luke Vibert who's track it was named after, where Posthuman are resident DJs. It won "Best Club Event" in DJ Magazine's Best of British awards 2019. In 2014 the clubnight launched a vinyl-only label also named I Love Acid. He also performed as one half of Altern 8's live shows between 2015 and 2020. Since 2021 Doherty has worked for the Mobineko Multimedia pressing plant.
