Easby, you're reading exactly the opposite of my point into my post.

I'm saying that those "rockers" are NOT part of the revival. But I am saying that those "rockers" stand on the shoulders of the revival -- that what those "rockers" owe the revival is that the revival, though having little spark of genius of it own, at least kept those instruments, that acoustic sound, alive long enough for real artists to come along and use it to make better music.

Those rockers were synthesizers (as are most good artists) and one of the elements they borrowed was a sound, a feel, from the folk revival. They also borrowed freely from jazz and from race recording and from whatever else was around -- but the sensibility -- the SOUND of their music comes greatly from the folk revival.
