The Ultimate Digital Easter Egg? How I Hid 25 Years of Music Inside a Silent WAV File. Buy the album here for any price you like. All money goes to charity.
When people think of Easter eggs, they usually think of DVDs, Blu-rays or video games.
Digital music files rarely contain hidden content.
That’s why I think this might be the ultimate digital Easter egg.
The Album: Remix Everything Classical
The track appears on Remix Everything Classical, a Bandcamp charity project where artists remix famous pieces of classical music in different genres.
The album is full of rave-inspired takes on classical compositions.
My contribution to the project, released under my artist name Backmasker, was a remix of John Cage’s experimental piece 4:33.
What Is John Cage’s 4:33?
If you’ve never encountered 4:33, it is one of the most unusual pieces of music ever written.
The performer is instructed to make no sound at all for four minutes and thirty-three seconds.
The idea is that the sounds around you become the performance.
So, when you play my remix of 4:33, you get exactly what you’d expect:
Four minutes and thirty-three seconds of silence.
Or at least, that’s what it seems.
A Clue Hidden on the Artwork
The cover artwork includes instructions for a piece of software called Minimodem.
Most listeners will probably ignore them.
But anyone curious enough to follow the instructions will discover that the file isn’t silent at all.
Running the command reveals a hidden message.
The Secret Hidden Inside the WAV File
Open the track in Audacity and it looks completely empty.
However, switch to Spectrogram View and you’ll see faint patterns hidden within the audio.
These patterns are modem tones. They’re far too quiet for humans to hear, but a computer can decode them.
The decoded message includes the line:
“I’d like to give you 25 years of my creative output. In fact, I already have.”
It then provides further instructions.
Everything in Nothing
The instructions eventually reveal the real secret.
Hidden inside the WAV file itself is a ZIP archive containing my music.
The WAV file isn’t just carrying a hidden message—it also has an entire compressed archive appended to the end of it.
Extract the ZIP file and you’ll uncover a hidden album called Everything in Nothing.
And this isn’t just a few bonus tracks.
The archive contains:
- More than 50 music tracks
- Around five music videos
- A huge collection of material that I’ve created as Backmasker over the last 25 years
In other words, I hid almost my entire musical catalogue inside what appears to be a completely silent audio file.
Hiding Everything in Nothing
I have been collecting media that contains hidden content for over 20 years and have made many pieces of music that contain secret messages.
But this project feels especially appropriate.
A piece of music that appears to contain nothing actually contains everything.
A silent WAV file hides an entire ZIP archive of songs and videos.
And that, to me, might just be the ultimate digital Easter egg.
Outer Release: 4:33 (Remix) by Backmasker
Hidden Release: Everything in Nothing
Secret: A ZIP archive containing 25 years of music and videos hidden inside a seemingly silent WAV file.
For obvious reasons, I’m slightly biased here—I created the release myself—but I still can’t think of a better example of an Easter egg than hiding an entire creative archive inside four minutes and thirty-three seconds of apparent silence.
