A fresh high school year always means much to come, and one of those things is joining a club. Being in a dilemma about which club to join, Yui Hirasawa stumbles upon and applies for the Light Music Club, which she misinterprets to be about playing simple instruments, such as castanets. Unable to play an instrument, she decides to visit to apologize and quit.

Meanwhile, the Light Music Club faces disbandment due to a lack of members. This causes the club members to offer anything, from food to slacking off during club time, in order to convince Yui to join. Despite their efforts, Yui insists on leaving due to her lack of musical experience. As a last resort, they play a piece for Yui, which sparks her fiery passion and finally convinces her to join the club.

From then onward, it is just plain messing around with bits and pieces of practice. The members of the Light Music Club are ready to make their time together a delightful one!

I loved this anime. But my reasons for it may be a little unusual. Let me tell you why. This review will encompass both seasons, because it kind of needs to, but I will avoid spoilers.

K-on is a story of four or five girls who form a light music club and spend their time messing around, eating cake and drinking tea, and sometimes, as an afterthought, playing music. That's the whole plot. There's nothing else.

... is what I'd like to say, but that's a gross oversimplification. It's so much more than that.

This anime starts a little slow. The ...

The way I look at things, getting children into music is never a bad thing, it gives them something to focus on, enhances the brain and can be a future for some, be it as a musician or any of the jobs with a musical need. Well at least thats before starting K-On, some ways should't be used to get kids into music, especially when it dumbs it down to the lowest level.

Story - 2/10

Even though the show sells itself as a music/band show, a majority of the time it's a slice of life/school show, with just a bit of musical talk in-between.

It's not a ...
