As the frontman of Machine Head, Robb Flynn is no stranger to a riff or two, but even he was stunned by the unrelenting attack of their 1994 EP, None, and took them on the road in Europe. As he sits down for a chat with Meshuggah axeman Mårten Hagström, on the eve of the release of the Swedish band’s 11th album, Immutable, the camaraderie and mutual respect between the two is undeniable. And while Mårten excitingly reveals he has enough leftover material from Immutable’s writing sessions for “three different albums”, it’s the band’s journey we’re interested in today. From Mårten meeting drummer Tomas Haake at school, to their detour into carpentry, to picking up an eight-string guitar, it’s been an extraordinary evolution.
