Well, the rock band could be made up of characters from different houses in Hogwarts. They might face a lot of internal conflict at first because of their different house loyalties. But as they bond over their love for music, they become a united front. Their music could be inspired by the magic and mystery of the wizarding world. Maybe they write songs about the Forbidden Forest or the secrets of the Chamber of Secrets. And they could use their music to fight against dark forces that are starting to emerge in the wizarding world again.
One idea could be that the members of the rock band are secretly wizards and use their magic to enhance their performances. For example, they could make their instruments levitate during a show. Another plot could be that the band discovers a magical spell that gives their music the power to heal people. Or perhaps they are on a quest to find a rare magical instrument that was once used by a great wizard and is said to make the most amazing music.
A possible plot for a Harry Potter rock band fanfic is that the band is formed in Hogwarts. They start out as just a group of friends who love music, but as they practice, they realize that their music has a strange effect on the magical creatures around the school. Some creatures are drawn to it, while others seem to be repelled. This leads to all kinds of adventures as they try to understand and control this power. They might also get into trouble with the school authorities for causing such disruptions with their music.
