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 hats are the melodies of the seven tracks of the first LP of The Low End Theory (1991) by A Tribe Called Quest, converted into seven knitting patterns. Each pattern is made up in Scotland as a traditional Fair Isle pullover using Shetland yarns. The hat is knitted as a rectangular piece of fabric, seamed up one side, and then gathered in to the centre by hand with a draw-thread, before being hand sewn into place.
