I believe it too. It was an interesting article but like I said earlier, it's nothing new. It only seems innovative because there appears to have been a large scale abandonment of that way of recording so if someone does it, it's like "Wow !".
It reminds me of maggots and leeches {not the band !}. Back in the day, when people in hospital had weeping sores and leaky flesh wounds, hospital staff would put maggots or leeches on the arm, leg or whatever, of the patient. The little critturs would eat the loose skin and gorge on the blood, thus cleaning the wound and promoting healing to the affected areas. Then as medicine "progressed", new drugs were synthesized and technology began to make it's presence felt, it was felt that we could do away with all those primitive, outmoded forms of medicine so the leeches and maggots were consigned to history, looked upon with a laughing looking back at how ridiculous things once were {like dentists giving cocaine to patients, or boffing people on the head with a hammer/giving lots of whiskey in the days when there were no anasthetics}. Fast forward a couple of centuries to sometime around the early 1990s and some doctors found that actually, the maggots and leeches had their place after all and began using them again and there are those that breed them exclusively for this purpose. And news reports at the time hailed this as a new wonderful innovation, thus causing it to look like the triumph of organic nature over soulless, impersonal modern techhnology.
The Foo fighters are simply the maggots and leeches of now.
