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 cutie mark is the mirror image of two eighth notes.

Her name is first mentioned in official material in the Equestria Girls commercial, which also references bronies and other online Friendship is Magic phenomena.
