Composed entirely by Stivell, featuring instrumental arrangements by Stivell assisted by Christopher Hayward and Michel Prezman, and with over 70 musicians contributing, this was a large undertaking. As well as embracing the classic Stivell fare of Breton, Scottish and Irish instrumentation, this early nod at world music includes oriental and African sounds as well as a full orchestra and lavish production values. On the original vinyl release, the "three circle" symphonic construction was emphasised in the track listings to a greater extent than with the subsequent CD reissue.
