Sure why not here's another band AU idea
So a couple weeks ago I saw this band named Hooky. They're a duo from Philly, playing a sort of indie rock/bedroom pop/electronica kinda thing: one guy sings while playing guitar, the other controls the electronics and autotune and stuff. It was kind of a funny sight because the guitar guy was standing relatively still while the electronics guy was going really hard at the DJ board. Here's a video of them to demonstrate what I'm talking about:
and it got me thinking: imagine if, like, the disaster twins decided to form a band with just the two of them, it would probably look something like that. I was thinking Donnie would probably go in a mask and outfit disguise while Leo gets a cloaking brooch somehow but Donnie could just don (pun not intended) a purple satin jacket and call it a day lol (especially since he's a little more blase with that sort of thing in the cartoon, especially at April's school).
Or if, like, sometime decades in the future, Donnie has a kid who gets into making EDM and then somehow connects with some budding indie/bedroom pop artist topside, ending up making music together that sounds kinda like this. And when they do gigs, looking kinda like that clip, the mutant turtle has to disguise themself in a suit or something Deadmau5-style while manning the boards lol.
