THE biggest single influence on A Foul Form is revealed by its closing track, a faithfully scuzzy cover of Rudimentary Peni’s 1982 song “Sacrifice”. The righteous 51-second blast is typical of the enigmatic trio’s curdled worldview, a brutal but necessary defrocking of organised religion (“In the eyes of the lord, everyone’s a servant”). It’s a timely tip of the hat given Rudimentary Peni’s unexpected return last year with The Great War, their first new music in 12 years.
