From the artists' website:
Flat Earth Society proposes a transposition of the earth elevation at the scale of a microgroove record. This engraving of elevation’s data on the surface of the disk generates in consequence a subtle image of the earth. When played on a turntable, the chain of elevation data crossed by the needle can be heard.
From the Avoka website:
DYSKOGRAF is a graphic disk reader. Each disc is created by visitors to the installation by way of felt tip pens provided for their use. The mechanism then reads the disk, translating the drawing into a musical sequence.
The installation is above all a tool, which allows the creation of musical sequences in an intuitive way. The notion of a loop, closely linked to electronic music, is represented here by the cycle of the disk. The disk passes indefinitely in front of a camera fixed onto an arm. This substitution for the needle converts the drawing into sound by way of a specific application program (software). Through this system, the sequential ordering of music is learnt in a playful way, at the same time creating a unique object, souvenir of the musical composition.
Yuri Suzuki, The Sound Of The Earth
From the artist's website:
The Sound of the Earth is a content of Yuri Suzuki`s spherical record project, the grooves representing the outlines of the geographic land mass.
Each country on the disc is engraved with a different sound, as the needle passes over it plays field recordings collected by Yuri Suzuki from around the world over the course of four years; traditional folk music, national anthems, popular music and spoken word broadcasts.
An aural journey around the world in 30 minutes.

A fantastic piece from a few years ago by Katie Paterson comprising sound recordings of glaciers pressed into records made of ice:
Sound recordings from three glaciers in Iceland, pressed into three records, cast, and frozen with the meltwater from each of these glaciers, and played on three turntables until they completely melt. The records were played once and now exist as three digital films. The turntables begin playing together, and for the first ten minutes as the needles trace their way around, the sounds from each glacier merge in and out with the sounds the ice itself creates. The needle catches on the last loop, and the records play for nearly two hours, until completely melted.
