In the winter of 2005 Marcus McShane set off to cycle from Los Angeles to New York on his 1998 Avanti Compeditor. Over this 63 day odyssey he wrote on his laptop, providing a view of America from the sidelines of its superhighways. Nag reflects this journey, and McShane’s obsessions with efficiency, bicycles, and the artist’s means of driving themself to produce. A self‐powered studio was built, where customised bicycles supply the energy to run laptops, printers, worklights, and a record player. This mechanism ejected printed rants and digital drawings as two artists furiously tried to keep up with their imaginations and dwindling power supply.
