This is track #4 from the album There. 

The sounds produced by processing samples from traditional and folkloric  music of Iran to make a rich and tense musical space. The samples are processed brutally and fractured totally in order to build up a strong tension.
The voice is from a recording of Ahmad Shamlu reading one of his poems in 1990 which is written in when he was in prison 1954. It is a letter to his father and it's called   'Letter to Father' 'نامه به پدر'.

The album is long waiting to be published by Entr'acte, hope it will be out Feb 2014.
