Why would you say it's co-incidence?
The area was designed as a giant, open air amphitheater. It's not co-incidence that they built it that way. It was necessary because they didn't have amplification back then, and for the priest/speaker to be heard, it had to be built acoustically near perfect. I think you get the same thing if you clap in a Greek amphitheater.
(But perhaps you just mean the bird sound and the (mispronounced) name being co-incidence? If so, nevermind!)

no producer worth his salt would do so little acoustic treatment to a square box room like that.

Amazing Acoustics! Halo theme sung in an oil chamber. has been added as a related post - related requested by RFlagg on that post.

The sound we hear hasn't got anything to do with the drums played in the video, other than faint thuds from hitting the pads - watch the drum fill at 0:29 - he plays a drum fill, but we still hear the regular drums from the original track.

As well - even if this was a "proper" rock band recording, you'd only trigger the pre-recorded sounds anyway, save for the odd drum fill.

For a Rock Band session to qualify as a livemusic, in my opinion, you'd have to overdub the drums with the sounds generated from a proper drumkit - electronic or acoustic.

And yes, I own and play rock band myself - I have an Alesis Dm10 kit hooked up with MIDI for proper drums, the Rock Band Keyboard for proper keyboard and the Fender Squier plastic fantastic "Strat" for MIDI guitar. It is especially fun with friends and beer.

Woodpecker made a wise acoustical choice!

It's great Thanks for the link. The acoustics of the train station work really well for it too... it sounds like a big cathedral.

i think most of you are missing the point that tom jenkinson is and has always been making, which is to pull complex and emotionally driven music from both man and machine by pushing both to extremes. to say it's "soulless" is to wear your confirmation bias and ignorance on your sleeve.

Sometimes the original or just the acoustics are enough to make a song good. Is this version commercially available somewhere? I'm part of the sad people who only recognize and know the popular one. And hearing the original is just as good as hearing the edited version.

It's been tested and the "best" audiophiles can't hear differences between 14bit and 16bit, nor can they hear differences between 44.khz and ANYTHING higher. In some tests they could use12bit sound with 36khz sampling frequency... The differences they hear are inside their head. Thus the description of improved sound is always "air", "brilliance", "organic" etc.. Don't be fooled by their fancy gear, most of it is for nothing. Cables: i am always willing to bet my months salary on doubleblind tests, 10 000€/m against a coat hanger, no audible differences.. It's all about confirmation bias, you think there's a change and suddenly you hear it.

About MP3s vs PCM:
Here we have audible differences. But. Put on high enough energy, ie turn your amp high enough, suddenly double blind studies can't find which is which. But it can be audible, mp3 is lossy format and even 320kbps can be heard. Not with all material, it's about in the limits of human hearing. Some might hear high end loss, if you're in your twenties. Once you hit 40, everything above 17khz is gone, forever. You will never hear 20k again. And to really notice the difference, you need good gear. Your laptop earphone output most likely won't even output anything past 18khz well and it's dynamic range can be represented with 8bit depth.. It can be just horrible. Fix that with usb box, around 80€: you can take that box anywhere on planet to the most "hifiest" guy out there and he can't hear the difference between his 10000€ A/D converter.. In fact, 5€ A/D converter can produce the same output as 3000€ one... That's not why i said buy a external.. It's more to do with RF and other shielding, protection against the noises a computer makes than A/D conversion quality. Note, i'm talking about audible differences, you can find faults with measuring equipment and 95% of the gear price is about "just to be sure".

If you want a good sound, first, treat your room. Dampen it, shape it.. If you spent 10k on stereo and 0 on acoustics, you will not have a good sound no matter what you do. Spend the same amount on acoustics than what you do on you equipment, room makes a lot more differences than gear. Next comes speakers, they are the worst link in the chain by a large margin. Quality costs, still wouldn't go to extremes here either, the changes are again "just to be sure", not always audible.. Then amps, beefy, low noise, A/B. You don't need to spend a huge lot of money but some. Then cables.. Take the 50€ version instead of 300€ or 3000€. Build quality and connectors, durability. Those are the reason to buy more expensive than 5€. Not because of sound quality.. There will always be group of people that will swear they can hear the differences, that's bullcrap. Human ear CAN NOT detect any chances, even meters are having a REALLY hard time getting any changes. You need to either amp up the signal to saturation point, or use frequencies in the Mhz ranges, thousands of times higher than what media needs to get any changes between cheapest crap and high end scams.

Audiophiles can't be convinced they are wrong, they are suffering from the same thing antivax people do: give them facts, they will be even more convinced they are right.
