Sonic Sound Singing Machine:
The invention of Ol-Tone, father of Jazz, best friend of Able DeVille.
By using high note tones it was able for Ol-Tone to break out of a prison of Magma, when he was learning the secret of Rock. When having a metal tool and you use high notes to sing against the stone, it will brittle, even if just in the beginning in little pieces, later on the brittling will becoming bigger and it is possible to work your way even trough solid basalt.
In the end stone and tar are equal kind of materials. One is liquid, the other not.
Sonic sound is the savior of the day, to brittle your way out of rock.
