Shirobako, Hibike! Euphonium Recommendations
Friendship, drama and dreams. The shows are about the heroines, and their friends, working hard to achieve their goals and dreams.
Shirobako is about the challenges which people face starting a career you're passionate about, and the ways people deal with them. Hibike! Euphonium is about the same topic – the challenges Kumiko faces in a high school brass band trying to qualify for the national competition. Both anime explore where the character finds their motivation, and the importance of their friendships in overcoming challenges.
Both shows manage to bring to life a very broad cast of characters focusing to achieve a single goal. At the end of both shows we know who everyone is, what is their line of work/instrument and roughly what their personality is like (especially with Shirobako).
