An advert for the new Boards of Canada album has been broadcast on Adult Swim – possibly giving out the last part of the six-piece code that’s been setting the internet alight.

Confirmed as legit by the network’s Jason DeMarco, you can watch the ad above. It broadcasts the same numbers as the NPR advert that was played earlier this week, but points to the first placement in the six-part code that has so far been publicised via limited vinyl releases, mysterious radio clips and the banner of a Boards of Canada fansite – meaning, we presume, that the NPR code that had been talked up as the fifth entry in the overall code is actually the first part, giving us this overall:

699742 / 628315 / 717228 / 936557 / —— / 519225

Now, given that the Adult Swim advert is by some distance the longest and most visual Boards of Canada advert yet (including a sizeable intro), it seems strange that it would simply be used to repeat the same numbers used in the NPR advert. Theories – which, it should be stressed, are currently unconfirmed – are now circulating on Reddit that, when the first half of the advert is played backwards, you appear to hear a second set of numbers: 347996. You can hear the reversed advert here:

So, if this reversed theory is true, then the overall code would be 699742 / 628315 / 717228 / 936557 / 347996 / 519225. But what does it all mean exactly? We’re not too sure, but it seems safe to presume that Boards of Canada’s first album since 2005 is on the way – that or they’re starring in a new Pepsi ad.

Confused? It’s understandable. You can read up on the Boards of Canada mystery so far here.
