Massive thanks to reddit user cnacker for discovering this!!
Hella's second full length album, The Devil Isn't Red, was released in 2004. Thirteen years later, a hidden song has been revealed.
There is a demo version of "Your DJ Children", from Total Bugs Bunny on Wild Bass, contained within the pre-gap information of "Hello Great Architect of the Universe" from The Devil Isn't Red. To hear this demo, rewind the first song on the CD or extract it from the CD to your computer. This requires a program such as Exact Audio Copy. After setting it up, rip the first song. If your cd drive was unable to automatically obtain the hidden demo, there is a step-by-step tutorial on how to change the settings to find it.
