Is There a Band in K-On?

The music was great and unique to me in the sense that they showed like for example, she's playing and I'm not a musician, right? So I can't really tell what's going on when the band is playing if they're like butchering it. The other music anime I really like is the kids on the slope. That has an insane vibe. It wasn't exactly the same as like a band was singing, but the vibe was. And yeah, I really appreciate of the show W after W there. It shows you the journey of getting the best out of yourself.
