Godspeed Track- where can I find it?

Music Gods-

I recently attended a dance recital that included the Godspeed You Black
Emperor track 'Hung Over as the Queen of Maida Vale'. The track was amazing-
even better than the hot female dancers gyrating to the insane beat and
esoteric wisdom spewing from Godspeed.

Question- since this was an unreleased track- how can I find it? I need it bad.
Please help.

You don't need it bad.
