Scottish electronica icons Boards of Canada began releasing eerie and evocative EPs in the late '90s, quickly earning a cult following among IDM fans. On their groundbreaking '98 debut album Music Has the Right to Children, BoC revived the spooky old-school synthesizer sounds of the '60s and '70s, adding crunchy hip-hop breaks and fuzzy techno beats. Despite typically long delays between albums, BoC has continued to evolve, whether that meant swirling in shoegaze guitars on 2005's The Campfire Headphase or dropping horror film keyboards on 2013's Tomorrow's Harvest.
