Maksim Chmerkovskiy will appear on the show Nov. 18 to judge the contest's semi-finals round. Maksim Chmerkovskiy appeared on many seasons of the reality show as a professional dancer.
The theme of the semifinals at which Chmerkovskiy will judge is “plugged/unplugged,” with the remaining dancers performing a paso doble, jazz, tango, or cha-cha routine to a normal version of their chosen song, according to ABC writer Jason Leung. The partners will then perform an Argentine tango, rumba, or Viennese waltz to an acoustic version of that same song.
According to Leung, this is the first time the “plugged/unplugged” theme will have been used on the show.
The night will also include a number performed by the remaining professional dancers that will be choreographed by Mandy Moore. Musicians Kerli and Noah Guthrie will perform songs during the “unplugged section,” according to Leung, with Kerli performing a version of the Fall Out Boy song “My Songs Know What You Did in the Dark (Light ‘Em Up)” and Guthrie singing a cover of LMFAO’s song “Sexy and I Know It.”
