Even without music, Korean boy band SEVENTEEN know their songs well to the point they can dance each step in sync with the song even if they cannot hear it.
A video was uploaded in Youtube featuring the band dancing to the tune of their song "Very Nice" for the Mcountdown Facebook live without them hearing the song itself. The boys had actually requested the writer to turn off the music in the first few lines of the song and they would dance it to the point it was actually in sync with the song.
After the song was done, the boys had watched the clip and were very amazed on how flawless the dance was even without music.
Look at the video below to see this extraordinary video:
