Vivid Sydney: the Avalanches' block party with DJ Shadow shuts down just as it's revving up

It takes a couple of hours to get going and then ends abruptly, but at its best, the Since I Left You block party is infectiously energetic and upbeat

The Sydney Harbour Bridge is outlined in luminous green. The skyscrapers on the skyline are dappled pink and teal, and under the sails of the Sydney Opera House punters gaze out over the harbour as ferries trundle past emblazoned with neon zoo animals – a tiger, a frog, a rhinoceros – and, just in case you hadn’t caught on to how all these things were supposed to make you feel, hashtags: #ILoveSydney, #Inspired.
