Blueschist is the third artist to be introduced to the Barrfparty label. The project is a mainly sound art project based around rocks and stones. The alias was developed for the Pinkamena Party album just rocks (for Maud Pie). The alias was originally named "Schist" upon the initial release of the compilation but was changed after the sync listen to Blueschist, as Lewis learned there was a rock with that name and liked it better. Three months after Blueschist released her debut album.
