History
When Rarity holds a fashion show for the Grand Galloping Gala dresses that she made for her friends, a unicorn pony wearing purple tinted sunglasses is seen for a brief moment using her unicorn magic to operate a turntable.

Her name is first mentioned in official material in the Equestria Girls commercial, which references many of the online FiM phenomena.

She's also commonly known as Vinyl Scratch.
