Cover art for Feathers  lyrics by A Perfect Circle

Feathers can be interpreted in a number of ways, but as a generality it seems to be a commentary on how talking, sharing, and being vulnerable can help to alleviate pain and break down the walls between people.

The metaphor of weight is used a lot: “all that matter”, “we carried”, “armor, anchor, lead, and stone” – and the lyrics specifically suggest that talking about it and working through it should lower that burden/weight: “By the telling, will they become – will they all be feathers?”

It’s not clear if the song is about a specific relationship between people, or perhaps something broader (e.g. countries). Source: https://genius.com/
