Well I can't fully digest the tracks that have been posted as there is a lot going on musically and the term 'Witch House' is awful as it barely resembles House music as I know it. It seems much closer to Darkwave to me Black Tape For A Blue Girl for example and certainly has echoes of Burial's ambience and Massive Attack's Mezzanine labyrinthine soundscapes but I really like what I am hearing.
Further investigation needed! Canwll I would heartily recommend the band Demdike Stare to you.
