Posthuman is primarily a duo of Richard Bevan and Joshu Doherty. Known mainly for multi-layered electronic music, with heavy emphasis on intricate drum programming. A signature to their sound is the extensive use of Roland 808 and 909 drum machines.

Although the bulk of their early releases fall within the IDM genre, Posthuman have been known to widely experiment, their 2002 self-titled EP combined hip hop and Heavy Metal with electronica, and their 2006 album The People's Republic was heavily influenced by post-rock. Nearly all of their output since 2007 has been techno and electronica, with much of it still being released physically on vinyl or CD.
