Boards of Canada remain one of the most compelling and enigmatic electronic acts in modern music. Emerging from the 1990s IDM scene, they carved out a singular aesthetic with their 1998 debut album, Music Has the Right to Children, a landmark release of bucolic VHS trip-hop psychedelia that bridged nostalgic memory and imagined futures. The duo's retreat from the public eye - marked by a lack of interviews and a hiatus from live performance - has fuelled decades of fan speculation. Interpretations of their work range from mathematical puzzles to apocalyptic prophecies and references to Sesame Street or end-times cults. Magic Window incorporates original interviews with musicians (cLOUDDEAD, DJ Food), music journalists (Simon Reynolds, David Stubbs), and key members of the BOC fan community, alongside an exploration of the band's cultural and media influences. Tracing their body of work from unheard early recordings to their 2026 release Inferno, the book provides an in-depth study of how Boards of Canada's music accesses 'the outside' - a realm existing beyond dogmatic belief, contemporary existence, and linear time.
