The earliest computer systems used punchcards adapted from knitting machines. Pop Punch is a collaborative conceptual project with a coder and a sound designer: between the three of us we’ve come up with a programme which converts the tracks of a vinyl LP into knitting patterns.

These cardigans are the melodies of three tracks from the Monk’s Dream LP (1952) by The Thelonious Monk Quartet, and three from J S Bach’s Goldberg Variations as recorded in 1955 by Glenn Gould, converted into three knitting patterns. Each pattern is a combination of a track from each LP, switching between the two whenever the music meets at a common note. The cardigans are made up in Scotland as a traditional Fair Isle, using dyed lambswool yarns and undyed natural grey Ryeland wool. The garment is styled after early 1960s knitwear, with contrasting long cuffs and a generous shawl collar which can be worn up or down.
