T-G-Invocation of My Demon Brother-FRIDAY: Anger (Jagger + Bobby Beausoleil *NOT CAJUN BAND - Manson Family 1964 )
The description Anger himself gives for Invocation of My Demon Brother is as follows: The shadowing forth of Our Lord Lucifer, as the Powers of Darkness gather at a midnight mass. The dance of the Magus undershirts around the Swirling Spiral Force, the solar swastika, until the Bringer of Light- Lucifer- breaks through.
From this it may mean that the ritual being performed is a sort of seance to "invoke" the devil. In that interpretation, Anger is saying that the devil must be his other side, his alter-ego, his "demon brother."
Music by Mick Jagger, appearance by Bobby Beausoleil (of the "Manson Family").
