For those uninitiated, Jem was an 80's cartoon and doll range from Hasbro [the same people who gave us Transformers, GI Joe, My Little Pony]. Jem was a singer with a duel role to play, because when she wasn't performing she was Jerrica the owner of Starlight Music. Jem and her band used holographic technology to change their appearance and control stage lighting. Her nemeses were The Misfits and their manipulative manager Eric.
And now for some Jem-spiration...
