The first season is 13 episodes and the second season is 24, so it's not too bad. There's also a movie as well.
It's about a group of high school girls who are trying to keep their school's light rock club afloat. Hilarity ensues in the typical KyoAni style.

Nagato from Haruhi:
Mio from K-ON!:
Tomoya from Clannad (probably the best example I could find in my quick Google search):
