Class Actress’ Sunday afternoon set at Fun Fun Fun Fest was nothing short of fun.

Lead singer of the 80s pop-inspired band, Elizabeth Harper, is all smiles on stage. She stepped out wearing a black three-piece pantsuit straight from a vintage store and kept removing layers of her outfit as the music progressed.

Harper is backed by producers and keyboardists Scott Rosenthal and Mark Richardson.

In an interview with ELLE, Harper cited Depeche Mode and Madonna as influences. This woman is living in the past—but it works.

Harper gained momentum in her energy during the entire set and had the whole audience dancing by the final song. 

One fan in particular who had behind the stage access walked out onto the stage while dancing and removing his shirt before a crew member grabbed him and pulled him off the stage.

“Weekend,” a song from Class Actress’ 2011 album “Rapprocher.” which is French for “to come closer to, shows off the band’s sound the best—Harper’s sultry voice fuses with the synthesized pop beats for a perfect laid-back dance song.
