Thanks Sean, this is what I've always thought it was, but the sound that Rod Dearlove at Thorne is trying to describe, could not have happened without a technically change. And it was that I needed a short and good explanation of which I got it early in the tread from garethx.
The discussion of what does fit this term is a never ending story it seems, I did not know that it had been discussed for years. So to guys like Brett, I'm sorry to bring it back on, but to me this forum is the best in the world when you need an answer to a questions related to soul music, and again I got my answer.
