Revision as of 02:08, 26 April 2013

April 20th, 2013 marked the 6th annual Record Store Day, a global celebration of independent record stores for which record labels produce special limited edition releases and reissues and distribute them for release on this date. On this date, reddit user lilcakey found a mysterious Boards of Canada 12" vinyl in Other Music, NYC. This vinyl provided one of six messages forming part of a 36-digit key. Following this event, more messages have been broadcast over different media. Despite initial skepticism, the AtalantaFugiens YouTube account (known to be official) updated the annotation on its Julie And Candy live video to briefly show the key format at time 4:19, confirming the legitimacy of the record.

Key and Message Format

The term key refers to the entire 36-digit / 1296 bit code. The term message refers to a broadcast which provides any number of digits from the key. The term message position refers to the position of the message within the key.

It is unclear at this stage whether the key represents a mathematical challenge, or an encrypted ciphertext, or a key for decoding some as-yet-unknown ciphertext. If it is ciphertext or an encryption key, then information theory (and in particular Shannon's noisy coding theorem) tells us that it is not useful information until the full message and its related key/cipher is known.

Key Format

The key is 36 digits long and numerical in nature. The message titles suggest that the key follows the format:
------ / ------ / ------ / ------ / ------ / ------
So far, we know the following 18 digits in the key:
------ / ------ / 717228 / 936557 / ------ / 519225
And the message 699742 has been broadcast without a title to divulge its position. This message can be placed in the key once the positions and bits of the remaining two messages are known.

Message Format

The messages are distributed by 45 second audio sequences following a set format:

a shortwave-radio-like noise floor with a numbers station sample being played quietly and noisily throughout.
a musical callsign announcing that a message is ready to be played
a 6 digit numerical message being read in a distorted, computerised manner

Each message is partnered by a textual 'title' of the following format.
------ / ------ / ------ / XXXXXX / ------ / ------
The 6 digit message is taken to fit into the marked six positions in the title. There is nothing at this stage to say that each message will be broadcast continuously, and the following title, for example, would not be impossible or unheard of in other schemes:
---XXX / XXX--- / ------ / ------ / ------ / ------

Message Distribution

Vinyl

The vinyl found in Other Music is a 12" record found in a sleeve bearing the following marking

BOARDS OF CANADA

------ / ------ / ------ / XXXXXX / ------ / ------

(P) 2013 WARP RECORDS LIMITED (C) 2013 WARP RECORDS LIMITED

The message on the vinyl is "9 3 6 5 5 7" and can be heard here. According to a store employee, the record was hand-delivered by a Warp Records representative and is one of only 6 in the world. One other identical copy has been found in Rough Trade East, London.

YouTube Video

->

On the 22nd April, the AtalantaFugiens YouTube account again updated the annotations for the "Julie And Candy" live video to briefly flash for 0.1 seconds "ONE GOT FAT" at time 4:20 (video 1), in reference to the source video for an Everything You Do Is A Balloon fan video (fig 2). Also at this point the Boards of Canada YouTube account updated its top favourite video to "Everything You Do Is A Balloon" fan video. On that fan video, a comment from a YouTube account hellinterface links to the nuevas semillas private video (video 3) shown above with interesting graphics from little house on the prairie. That private video contains a link to the fourth video (video 4) shown above in which the new message is played (with digits 717228) and the message position is flashed on screen.

Radio

On the evening (GMT) of 23rd April, Zane Lowe played the sixth message of the key on BBC Radio One. Upon consulting the show's playlist on the BBC website, it lists a track by Artist: Unknown, Title: ------ / ------ / ------ / ------ / ------ / XXXXXX. The message was 519225.

On the evening (EST) of the same day, NPR played another message on All Songs Considered. This message was 699742. The title is unknown and therefore the message position has not been confirmed, although when future messages are broadcast then this can be deduced.
