They played right after Mars Volta at Big Day Out last year and NONE of the Americans got it...........I sure didn't but the Aussies seemed to dig on them a bit.I had never heard of them and I am in the music industry for 24 years now.I am guessing they were big in OZ but not over here in the US.I saw a dvd recorded at the same place in Newcastle that ZZ just played last month,it it the same one? I am thinking its the same place....they are big over there I see.
