In contrast to the darker doom path that Grief Collector established with 2019’s From Dissension To Avowal, their first proper full-length shows more direct connections to singer Robert Lowe’s past projects. ‘Corridors’ opens En Delirium (Petrichor Records) in a similar fashion that ‘Falling’ started off Solitude Aeturnus’s Through The Darkest Hour, featuring a catchy Grunge groove and lofty vocal lines. There are even some Classic Metal touches comparable to the most recent Tyrant album on ‘Our Poisonous Ways’ and ‘The Letting Go.’
