Still think it's strange that when it comes to Down Under bands some people immediately think of Crowded House and Men At Work when neither sold anything like the number of records that AC/DC shipped.
I don't think sales are necessarily a good measure of 'quality' for me. By that measure you'd have mention Jason Donovan, Kylie, Savage Garden, Delta Goodrum, Rolf, etc.
I'm not saying ACDC aren't a great band, just that more sales don't always equal 'great', but you are right that Angus and co are often over looked.
Personally I liked Split Enz - which partly feeds into Crowded House and then Finn, etc.
