I don't know, but a friend of mine does. (I'll find out where he finds his tips.)
Also: LUNA PARK has a lot of concerts. It' is about a 2,000-4,000 seat arena thing. The range of bands that play there spans the gamut. They also sell tickets to other events in town.
As the weather warms up down here (thus cooling off north of the hemisphere) a lot of bigger bands come for a visit. I saw the Killers at a large stadium last year. There are also some music festivals.
