The double vox work well.
Has a Diamond Dogs feel to it except with the guitar sounds from The Man Who Sold the World or Saviour Machine.
One of those two guitars (Saviour machine one?) could do with more sustained notes & fewer trills to sustain the power of the emotion. Flourishes don't have the same emotive power, to my way of hearing, as sustained and languidly bent notes.
VERY, VERY good piece however.
Organ (?) underpins things nicely.
