I completely forgot to go and see this. As part of the Good Diversions project, the artist group known as 'Foreign Investment' performed a couple of music events responding to the City in Transition.

On Wednesday July 5th 2006 they were on one of the building sites and on Thursday 6th they were on a horse and cart traveling along Berry St and Bold St to Williamson Sq.
