The DC TV shows on The CW have been crossing over with each other ever since the very first episode of The Flash, and the crossovers have only gotten bigger in the years since. The announcement of a musical crossover between The Flash and Supergirl came as a surprise to many last year. After all, as crazy as both shows can get sometimes, bursting into song for no reason didn't sound like something that would make any sense on either series. Yet, it will be happening and now superhero super-producer Greg Berlanti has revealed the villain who will have the ability to force folks into song, saying this:
It is going to be the Music Meister. We're finishing writing the script this weekend. We haven't gone about casting it yet. But it's the right question, though.
Music Meister is a relatively little-known villain from DC TV history, but he should be perfect for the Flash/Supergirl crossover just by virtue of having "music" in his name. Greg Berlanti and Co. were charged with finding the perfect bad guy who could somehow compel characters to sing, and Music Meister should fit the bill. Berlanti's reveal came at the TCA press tour (via EW), and it's a solid reason for fans to get excited about the musical meet-up.
The villain Music Meister was created for the Batman: The Brave and the Bold animated series. He appeared for the first time in the episode "Mayhem of the Music Meister," and he wreaked havoc on heroes and villains alike with his hypnotic singing voice that allowed him to control minds. He could force those affected by his voice to express themselves only via the arts of song and dance as if they were in a real-life musical, and he created a lot of trouble for Batman.
Although the debut of Music Meister is pretty bad news for the characters of The Flash and Supergirl, it's pretty great news for those of us who have been wanting to see the cast dust off their pipes and sing on their respective shows. Prior to landing their superhero roles, Grant Gustin and Melissa Benoist were best known for playing characters on Glee, and both Jesse L. Martin and Jeremy Jordan have Broadway experience. Flash viewers got to see the Earth-2 version of Joe West croon some tunes in a Season 2 episode, but it was far too brief of a song to really showcase Martin's talents. Hopefully we'll get to hear more of him in the musical crossover. Who knows? Maybe if Greg Berlanti can find a way to bring Malcolm Merlyn into the mix, John Barrowman could sing as well. Hopefully for all of our sakes, Caitlin Snow will have learned from her disastrous Season 1 karaoke experience and stay away from Music Meister.
Not many details have been released so far about the musical crossover. Neil Patrick Harris played the Music Meister on Batman: The Brave and the Bold, but he stated in 2016 that he hadn't been approached about reprising the role for the Flash and Supergirl crossover. We also don't know just yet whether the crossover will take place on The Flash's Earth-1 or over on Supergirl's Earth-38.
