New York based Peruvian sound artist Maria Chavez is publishing a book of essays and illustrations on turntablism, titled Of Technique: Chance Procedures On Turntable. The book is intended to work as a 'how to' manual with illustrations that are meant to be torn out and used as diagrams for learning to create different sounds and hand movements.
For her experimental turntablism, Chavez uses new and broken needles (the latter of which she refers to as 'perfect to ruin' needles), on a collection of vinyl she uses to build a sound palette.
Chavez has been an artist in residence at Issue Project Room, among other places, and played in Christian Marclay's Screenplay at the Whitney Museum in 2010.
Of Technique: Chance Procedures On Turntable is published by Printed Matter. More details here.
