I don't think there were any findamental failings in what was being done at the Apollo, I just reckon the engineer had had one too many sauces and missed a couple of things (like ACR's vocal being panned left, or the sax being almost silent, or Hooky's vocal mic apparently only coming out of the monitors much of the time.)
The actualy rumbling was beyond anyone's ability to fix, the room just rings. I (for the first time ever) didn't get a good look at what bass bins were in use, but the mid/tops flown beside the stages, were fucking impressive highly directional units, the plan presumably being to set up a direction arc of direct sound for the mid/top detail, and just leave the room to rumble away in the bottom).
Maybe I'm exaggerating because it struck a chord (quite literally) with my ailing guts, but you can hear it plain as day on the webcast, usually at the starts of songs, because someone or something rolls all the bass out of the feed after a wee while in.
Being at the front or in front of the tweeter stack may have given a nicer balance, but most places I stood there was FEARFUL resonance that threatenned to obliterate the band altogether. There was one point I distinctly remember watching Hooky play a riff, but every note sounded like the same pitch, because of the constant harmonics of the room (I'll spare you the explanation if you accept that such a thing can happen).
I'd like to hear the thoughts of others on the earthquale situation.
I'm not complaining or upset, I loved it apart from the violent gut betrayal....much rather hear someone take a rig to the very edge of death and back than fanny about all night. I'm not sure however that this rig ever got to that kind of level, i'm almost certain the limiting factor was the room itself, any more volume and serious problems could happen.
But I'm assuming the bottom end's generally not QUITE that runaway at NO gigs.
In my bootleg digesting experience NO gigs are a lot like our own, the engineering and mixing is usually really good, but prone to glaring fuckups. Apollo pretty much backed that up.
EDIT, are you sure about festivals being crap because they are outside? if you mix right outside it can be powerful enough to really mess with people's heads even the sober ones. More likely the reason NO don't sound as good at festivals is that their engineer and the festival head engineer have to mix by committee, and the fact that their gear gets dumped on the stage 5 mins before they do , and on they go with no soundcheck. Must admit I've heard some attrocious crap outside as well as the nice noises I mentioned, but still, i stand by it, that the open air can be wonderful if you know what you're at and your have the time.
