Roughly a year on from his last album, Xen, cutting-edge digital producer Alejandro Ghersi continues his stark exploration of shape-shifting digital realms. Where Xen explored his gender-fluid alter ego, Mutant is billed as more extroverted, explicitly referencing friends and colleagues. One of its finest passages - the epically chilling Snakes - is a nod to Ghersi’s former collaborator, Björk (both are snakes in the Chinese zodiac, he says ). Faggot, meanwhile, moves from probing equanimity to stark clanking as Ghersi seeks to reclaim the word. Perhaps the NSFW art and videos for Vanity and En skew the narrative, but Mutant feels even more sexual than its predecessor.
