elph.zwölf is one of two releases credited purely to ELpH, an alias for the group Coil.

This CD was number twelve in the series 20′ to 2000, published on the German label Raster-Noton.

The imprint -20'00"- on the disc itself may refer to the actual length of the track rather than being a title.

A speculated reason that Coil used their alias band name ELpH for this release, is that the German word for eleven is 'elf', and is a homophone with ELpH, while 'zwölf' means twelve in German, and the CD was the twelfth release of the series.

The CD is 5" in diameter, but only the inner 3" is playable as the outer edge is clear plastic.
