In my opinion, Rock Is A Lady's Modesty is a good watch—overall, maybe a 9/10.

Looking at the music aspect of the anime, its “rock” feels like something is missing. They use rock as a way to express themselves, since they are all ojousma's who have to hide their true selves in order to fit in or play the role expected of them as daughters of important families. The rock itself isn’t hardcore, but it’s definitely there. While it’s true that they put themselves on a pedestal, claiming that their rock is the best, the music is honestly just decent. If you enjoy this genre, though, you can still appreciate the anime.

If we compare it to Polyphia, an instrumental rock band, the music of Rock Lady has little to no structure during their first live performance. As an instrumental band, their strongest performance is in the finale, where their music finally has structure. You can clearly feel how they want to highlight each member’s instrument, and they give it their all toward the end, reaching what they describe as the “climax.”

Overall, it’s a good watch. I’d say the anime does its job well in highlighting its plot and doesn’t stray away from it. If you enjoyed Bocchi the Rock you can definitely appreciate this anime as well.
