Meet your Music Meister!

During the upcoming Flash–Supergirl musical crossover, Darren Criss makes his debut as the DC Comics villain who causes his victims to break out into song — and EW has the first look.

After being whammied by the Music Meister, Kara (Melissa Benoist) and Barry (Grant Gustin) find themselves trapped in an alternate reality in which life is like a movie musical. The only way to wake up? Follow the Meister’s script till the end. Kara and Barry’s friends are all characters within the movie, hence Winn (Jeremy Jordan) tickling the keys during a group number — which we reveal in this week’s issue of Entertainment Weekly.
