"Song of the Bell" follows earlier outings "September Song, pt. ii" and "The Right Thing Is Hard To Do".

Lead vocalist Audrey Kang says of the new single, ""Song of the Bell" is a song about hope, but it's also about understanding that uncertainty is an inextricable part of being alive. This was the last song to be written - we'd already recorded the bulk of the record. We were in the first leg of quarantine and I felt like our days had been abruptly hollowed out. I was thinking about emptiness and reading the Tao Te Ching, this very enlightened text, ‘to be empty is to be full, twist to be straight,’ etc. So I was thinking about that concept, how one can ‘empty’ oneself to be full, and where is that line, between emptying yourself and losing yourself? I thought about how when something is empty, you sort of have two choices: you can see it for what it used to hold and no longer does (i.e. a ‘shell’), or you can look for its potential to hold new things and possibilities (i.e. a ‘vessel’)."

A Color of the Sky will follow the band's 2019 second album October Song.

The seeds for their new album were planted after Kang attended a festival of kites. She explains, "I really didn't know what my life was going to look like, but at the kite festival, I knew that each day I'd see a lot of beautiful kites, and each evening I'd watch the sunset and sleep on the beach. I felt like nothing could hurt me."

Lightning Bug recorded their new album as a live band in a rundown old house in the Catskills that they turned into a makeshift studio. Kang says, "Songs in the past sometimes felt muddled, or I felt lost where to take them. But for this one, each song felt like a whole entity from conception."

She adds of the album, "I want listeners to explore their own interior worlds. It's about learning to trust yourself, about being deeply honest with yourself, and about how self-acceptance yields a selfless form of love."
