I used to sit in on a bunch of Specter's sessions.
I'd give Phil a lesson or two in engineering / producing once in a while.
Yea, he'd beg me over and over: "Chessrock ... please, teach me all of your secrets, and show me your audio tricks."
I got tired of him begging me, so one time I just sat him down and said: "Phil, 'ol buddy ... ya see, it's all in the track count." You see those paltry 23 tracks you're working with there? Child's play. That's not even in to the triple digits yet."
Later, he'd come back to me and say: "Chessrock .. okay, I just added 12 more tracks this afternoon. Will you listen to it? How did I do?"
After which I would procede to say: "12? Is that it? How long were you working on this? Do you mean to tell me that you spent an entire afternoon on this, and all you have to show for it is 12 more tracks? You're going to have to do better than that. Dude, my little 7-year old sister records 12 tracks in less than an hour. Quit being such a panzy."
After my stern rebukes of his laziness and general lack of track count ... Phil quickly went to work devising this "new recording technique" as he called it. And thus, the birth of what we now know as "The wall of Sound."
