The most obvious was the re-emergence of faster classic swing era and hot jazz music at dance events. People were now encouraged to work on their improvisation skills at faster tempos like they previously did to slower, groovier music.
This led people to mine and more vintage film clips for more ideas to move to this music instead of trying to force hip hop or other modern movements into the music. Since most of the Lindy Hop clips had already been found, the search expanded into tap and other jazz inspired black dancers of the past from the Nicholas Brothers to Josephine Baker.
