stamping mill

Stamping Mill is an American experimental rock band, founded in 2009 in Northern California. The sole member of the band, who goes by the pseudonym of Joseph, composes songs using a computer program to generate musical notes randomly. The structure and collections of tones within each song are predetermined, while the sequence of notes is selected randomly and then recorded using guitars or xylophones or other instruments. This style of music, in which some element of the composition is left to chance, is known as aleatoric music. Aleatoric music is primarily associated with classical composers like John Cage and Witold Lutoslawski and has only occasionally been used in the rock genre.

A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation.
