Boards of Canada don't take their music too lightly. In their rare interviews the duo wax philosophic on the manipulative possibilities of music and their interest in subliminal messages. Repeated listening to the tracks on this or any of their other albums makes you question a lot of what makes music "music", or even further, existence altogether. I don't want to veer too far off topic here, but the band has a lot of introspective weight behind their recordings, which definitely lures you into researching some of their meanderings. Some tracks when slowed down and played backwards reveal hidden spoken word passages... pretty interesting stuff that serves as a simple texturing element during conventional playback. They also reference numerologic and mathematical inspirations, in particular abundant numbers, which serve as their reasoning behind the name of their label Music70.
Campfire Headphase as a musical offering has some great beats and breakdowns, and the BOC use of analog devices really provides for a richly padded, intensley textured instrumental soundscape. "Dayvan Cowboy" is my favorite piece on this album, and I say "piece" not "song" in the same way I would refer to a "piece" of visual art. Their songs are really instances of artistic musical exploration, creating from a pallette of found sounds and unconventional sampling. I'm not prone to recommend this band to many people, fans of post-rock and experimental music are probably prepared for BOC and should take pleasure in their unique sonic adventures.
