Originally recorded in 2002 by Steven Stapleton and Colin Potter, the piece 'Salt' was a limited edition release to accompany an exhibition of Stapleton's artwork at The Horse Hospital in London. The following year 'Salt Marie Celeste' was released as a single 61 minute long piece of droning atmospheric sound that manages to be both minimal and maximal at the same time. A parade of strange, often unlikely, sounds appear and disappear during the voyage from Z to A.
