Slowly but surely, Class Actress’s Elizabeth Harper is making a push towards pop music’s inner-circle. She’s off to a great start, as her forthcoming Movies EP is executive produced by the star producer Giorgio Moroder, who has just released his own LP of some of the year’s most entertaining pop music. Class Actress’s EP is already responsible for one of the year’s best singles, “More Than You,” and the recently-shared “GFE” is another sign of the strides Harper has taken since 2011’s Rapprocher. The title stands for “Girl Friend Experience,” and the singer fully invests in the material. Harper’s songwriting has gotten sharper, and on “GFE” she shows Lana Del Rey-levels of specificity in her lyrics. “GFE” is not just a virtual-reality simulation; we also get to experience it.
