This book is about margins and marginality in the art world as sources for critical engagements in the studio. It builds on the pioneering work of critical theorist and artist Michael Betancourt, who has used glitches as an integral part of his art since the early 1990s. This book presents his thinking about his own work linking theory and practice in a larger context of conceptual and theoretical concerns that are neither a statement of intentions, nor merely a subjective series of claims about past accomplishments.
