There was no one quite like James Brown. From the T.A.M.I. Show, 1964:

Brown came on just before the Stones:

T.A.M.I. Show is particularly well known for James Brown's performance, which features his legendary dance moves and explosive energy. In interviews, Keith Richards of The Rolling Stones has claimed that choosing to follow Brown and The Famous Flames was the biggest mistake of their careers, because no matter how well they performed, they could not top him.

Or, as a YouTube commenter notes, "when mr. brown hit the stage, game over".
