What is "arandel"

Arandel is a french musical project. The album In D (a nod to Terry Riley In C album) lays the foundations of a dogma only allowing music instruments use and banning samplers and other MIDI devices. Encouraging the concept of a creator’s vanishing behind its creation, Arandel is an anonymous project, which members and actual composition remain unknown. To that end, any representation or identification of its contributors is prohibited, especially live photographs and videos.
