This Friday's episode of Artsnight (11pm, BBC2, 20 November) is presented by Edmund de Waal, with whom I had the great pleasure of working on Psalm.  Before the premiere last week I was interviewed for the programme, relating my work to Edmund's practice, and white (of course), and Celan, and memory, and the wonderful Aurora Orchestra, who performed my piece.  I may have been cut from the final edit, but perhaps I'm still there. . . tune in and find out!
