Acherontas has always been some kind of mysterious entity to me, and despite their last offering Amenti already being close to 2 years old, it still offers a fresh perspective with each listen. As though Amenti weren’t a sufficiently epic release, Ma IoN (Formulas of Reptilian Unification) builds on the style that the band has come to be known for, resulting in what is perhaps their most engaging and intriguing release thus far in their career.
