A lot of musical fans know Darren Criss as one of the ensemble characters from Fox's Glee. Heck, he's been Blaine for a couple of seasons, an openly gay and confident student who scored the first Billboard #1 Hit for the show with his cover of Katy Perry's Teenage Dreams. I know him as Harry F-ing Potter.
I first saw Darren Criss way back in 2009, or so, starring in A Very Potter Musical on Youtube. The musical is a Starkid fan production with music and lyrics written by Darren Criss and A.J. Holmes and a book written by by Matt Lang, Nick Lang, and Brian Holden. The musical is a full production piece that stretches out to three acts and is one of the most enjoyable finds I have ever watched on youtube. It lovingly satires J. K. Rowling's creations and tropes- from bumbling gay Dumbledore to blond haired bully Malfoy, and creates an amusing spectacle that no true Harry Potter or Darren Criss fan should miss out on.
