Sustaining the séance of their debut cassette, spectre-beat duo Hey Mother Death find Gondry/Björkian symmetry with chromatic visionary Heather Rappard. These ghostly exposures link up so perfectly with the spellbinding whispers, scorched guitars and splintered trip-hop that it’s difficult to imagine one without the other. This one screams Serious Art from start to finish, with nary an ironic wink in sight.
