On June 27th, rookie group, EPEX, dropped a new dance practice 'C9ROOKIES version' of 'Lock Down'.

C9ROOKIES is a previous name used for EPEX before they debuted. The outfits they are wearing (white dress shirts with jeans) were initially used in their teaser photos back when they went under that name. Seeing them dressed like this is definitely a trip back to the past!

What do you think of this special, 'C9ROOKIE' 'Lock Down' dance practice? Please let us know!
