Forgotten Songs, Angel Place, Sydney

Above is a photograph I took the other day of the installation/ artwork in Angel Place called Forgotten Songs. The Sydney City web page on the artwork says it is a visual and sonic piece as the calls of birds that used to inhabit the area can be heard as you wander beneath the bird cages. These songs also apparently change as the day progresses to reflect the daytime and nighttime activity of the birds that used to live in the Sydney city region. I think it's one of my favourite urban artworks.
