The band derives its name from the main concept of the show, which are the holographic images projected from Synergy, a supercomputer built by Jerrica's father, via her earrings. These earrings have remote micro-projectors in them, allowing Jerrica to assume the persona of her alter ego, Jem. She can also project images around her, which she uses in many cases as a distraction if her cover is about to be blown or to protect herself and her friends from danger.
The band has made much progress throughout the series, starting with their formation in the first episode, and would often reach the top of the charts. All of the band members are close friends, with Kimber Benton being Jem's sister, though the band has been separated a few times. Examples include: The Day the Music Died and The Bands Break Up.
