Boards of Canada – Music has the right to children
The first time I heard Boards of Canada was in 2013 and I immediately fell in love with their sound, which I would always describe as flying through a desert of ice. Honestly any work of them would qualify for tunnel.music.
Edit: I actually first heard Boards of Canada around 2005 and thought it was Portishead because a BoC track snuck into a folder of Portishead music on my PC. This album is an absolute masterpiece. Not just for ambient music, but music as a whole.
