Voivod are one of the founding fathers of modern prog metal thanks to a run of classic late 80s and early 90s albums that fused complex time-changes with head-spinning sci-fi concepts. In 2011, just before the band were due to revisit their classic album Dimension Hatröss at the Roaburn festival, drummer Michel ‘Away’ Langevin took Metal Hammer on an interstellar tour of his band’s career to that point.
