For a moment, the area goes dark, save for a spotlight in the stage area. It shines on a particular creature, one borne of darkness.
"Ladies and Gentlehumans and enemy forces--have we got a show for YOU! LIVE, from the streets of Spirale! A
"To hype up these LOVELY Talents! Say it with me, folks! It's..."
"And what better way to support our rock stars than to SCREEN! THEM! LIVE!"
"You folks at home--don't worry! You can support from the inside, too! We'll be hard at work putting up the lyrics to songs you might not know! Even a little hum helps, if you're brave! NOW!"
Televisions in the ward he's in light up with the image of his face--then to a broadcast of whomever is performing. It changes and rotates often when one song is done.
"Performers! Give it everything you've got!"
"Warriors! You've got to defend the power of song! Let's rock and roll! Let's get down! Let's JAM!"
One of the stages blooms to life with spotlights, mists, and--how'd that makeup get on some of your faces? That's scary, can he do that?--

What's Tenna doing for part 2? Entertaining, of course! While he could sing in theory, what he's doing instead is increasing the broadcasting ranges of songs others are singing. In addition to that, he'll be adding effects to inspire confidence and morale! If your muse is shy, he'll be there to gas them up and really put them in the performing mindset. (If you want to say he passively does this for your muse but don't want to make another thread, feel free!)
As the enemies are copying abilities, he's trying not to use his combat magic, but can in a pinch.
He might be under fire more often than not, which is. Not optimal. But he's inspired by the Lightners he's grown to know in his new home, and that's staving off the fear of bodily injury. (off-camera, it's probably easy to see him struggle. He didn't go into this unscathed from the moon.)
