You pretty much took the words out of my mouth. Yes Soundwave and Big Day Out are basically the two biggest (and IMO only ones worth going to) festivals in Australia. With that said, I don't think LP would get the greatest reception at Soundwave then they would at Rock AM Ring in Europe or something. Soundwave is normally full of Metal heads. And if LP come on and Play like Numb, Catalyst, Burn it Down, I personally don't think it would go well unless all the shit is like OSC, NMS, Given Up etc etc.
With that said, Ill go no matter what. But it would really fuck for us LP AUS fans having to deal with the massive crowds, sticking it out thought all the facts if we want to be at the barrier etc. Headlining their own tour would be a far better option. And fuck, with their production these days for their shows, I don't think Soundwave can cater a production like that. Just do a stadium tour and fuck the shit out of those shows.
