Easy. That's a recording of the 'I Have A Dream" speech. The cosest and clearest copy, became infused to the passion and soul of MLK Jr., Using it to record a voice allows an imprint of their being to be put onto the tape, and playing it back projects their emotions, willpower and essence into the listeners. No matter what's recorded, it always plays the same original audio, but with the voice of the last recorded person instead of King's. It only holds one voice at a time and can only be played once per recording, after that it reverts to "factory settings".

Used to record the soul of Garrett before his death and played a part in his revival.
