disagree there. He just got better and better. His death marked the end of soul music.
Soul music is still out there being sung live and recorded. Good news is the 80s synthesizers and disco beats are gone.
Many are older performers who never made it "back in the day" but others are new blood or session musicians stepping out on their own. Black and white performers in this game. Just like the old days.
Some names off the top of my head:
Charles Bradley (the screaming eagle of soul, a little over the top for my tastes but a good show)
Lee Fields
James Hunter
Sharon Jones
Renaldo Domino
Black Joe Lewis and the Honeybears
Not all of these are on Daptone or Desco Records.
There are more out there, consider this a starting place (and a number of these play the nightclub and festival circuits).
