A group of rebels fed up with pop culture decide to form a band to rebel against society with music, little did they know they would become one of the most controversial bands of all time.

I can see the fun in this one. I think using the word "rebel" twice detracts from the logline.

It might be better to start "Fed up with pop culture, a group of rebels..." I think it frames things better.

It's unclear who your protagonist is or what their goal will be. This logline boils down to "a band becomes famous." What sets this apart from a dozen other films like that?
