Slag tanz is not unknown to fans of Magma and that it is on the dvd Myths and legends Epok 5. Although it lacks a little finesse on the melodic level, the powerful rhythm of drums and Christian Vander bass Philippe Bussonet manages to create a dark and magical world. I regret that despite all the female voices, though usually present at Magma are somewhat overshadowed by the booming voice of Hervé Aknin ... though a little short, the whole is consistent and of good quality and shows, if necessary Magma was that still has the resource after 40 years of existence.
