Through Instagram, SHINee has released some more teaser images - but on top of that, this time, they also released the MV teaser!
Sound and image-wise, the boys are definitely going retro. Sound-wise, they sound like they're just jamming it out in the 80's, but image-wise, there seems to be some 90's mixed on in there.
What do you make of this oldies tune and concept for '1 of 1'?
