Sydney's Live Earth

Tens of thousands of environmentally minded music lovers have packed into Sydney's Aussie stadium for the first in the Live Earth series of global concerts.

The day's musical highlights have included Missy Higgins joining singer-songwriter Paul Kelly on stage for a duet and a fun-packed early set from Sneaky Sound System.

Eskimo Joe, Blue King Brown and Ghostwriters played early in the day, while headliners Crowded House, Wolfmother and Jack Johnson closed the event.
