Writing for performer and tape offers its own interesting tension: while the tape spools on regardless, unchangeable once the playback button has been pressed, the performer seeks a foothold for their own interpretation, emotions, temporal ebbs and flows - all the things that make a `live' performance a trilling wire, to meander along precariously, confidently, gladly or sadly, dependent on realtime circumstances and yearnings.

The title is taken from T.S. Eliot's Four Quartets.

... The trilling wire in the blood
Sings below inveterate scars
Appeasing long forgotten wars.
The dance along the artery
The circulation of the lymph
Are figured in the drift of stars ...
