Translation: "Liz and the Blue Bird"
I do not own the piece but felt like I needed to share it in its entirety.

First Movement - “Frequent Days” - 0:00
Second Movement - "New Family" - 4:53
Third Movement - "Decision for Love" - 9:50
Fourth Movement - "To the Distant Sky" - 16:12

This is the full-length piece of the song used in the films "Liz and the Blue Bird" and "Hibike! Euphonium: Chikai no Finale". I couldn't find a high-quality version already uploaded except for the separate movements, so I just put the movements together.
