Obviously, Stax played a huge part in the development and dissemination of soul music in general and Southern soul in particular, but I feel that the dogged focus on Stax and their artists obscures so much less "produced" Southern soul.
Who here listens regularly to music on labels like Jewel/Paula/Ronn, Hotlanta, Glades, or Sound Stage 7? Who here knows people like Jimmy Lewis (who actually had one single on Stax) or Roscoes Shelton and Robinson or Ted Taylor or Geater Davis? All SS artists of the highest order - not to mention better known names like O.V. Wright and James Carr.
Stax had the publicity (and the big-label money support), but there were so many other singers plying their trade at the time making far sweatier, more intense records that speak volumes to me about the time and place in which they were made. With some notable exceptions, Stax stuff just doesn't do this for me.
To make the situation worse, we have "expert reviewers" like AllMusic's resident reductionist Richie Unterberger telling us that almost everything soulful that wasn't recorded on McLemore Avenue between 1965 and 1975 was just a ripoff of the "Stax sound."
Sad.
