The Brothers were introduced by Siegfried Zielinski
We viewed sections of
Eurydice She, so Beloved (alludes to Rainer Maria Rilke's Sonnets to Orpheus):
Streets of Crocodiles:
Duet—Variations for the Convalescence of 'A'
and In Absentia (a collaboration with Karlheinz Stockhausen, this was based on Robert Walser's The Pencil Fields)
Andre Habib has an excellent interview with the Brothers that we might want to enjoy, here.
