Girls' Generation 'Mr.Mr.' Dance Practice

SMTOWN practice-room upload, March 2014. Girls' Generation built their reputation on large-group unison, and "Mr.Mr." is a late, sharp example of it from the group's peak years. The practice video is the cleanest way to judge the lines and spacing, since nothing cuts away when a formation changes. Watch it next to SHINee's "Sherlock" for two very different answers, from the same company, to the question of how to move a big group as one.
