Pennsylvania-based alternative rock project The Quality of Mercury today releases the single “Ganymede”, the first track issued from the forthcoming album “The Voyager”, due October 24, 2025. A digital pre-order for the album is live now on Bandcamp.

Jeremiah Rouse explains the song like this: “‘Ganymede’ is a love story told through the lens of science fiction. It follows two people who meet and fall for each other on a space station that’s orbiting in the golden atmosphere of Jupiter, a place full of warmth, wonder, and the thrill of possibility. He’s cautious. She’s fearless. And he follows her, chasing the gravity of her spirit.”

“But when she persuades him to explore Ganymede, a cold, sterile moon, the warmth between them starts to fade. The relationship fractures in the isolation and cold environment, and eventually, she walks away, leaving him alone at the edge of an airlock. This song is about how love can start bright and beautiful, but lose itself in unfamiliar terrain. I want listeners to feel like they’re watching a film unfold in slow motion and to feel the quiet heartbreak of trying to hold on to someone who’s already gone.”

Rouse wrote, performed and recorded the material, with drums performed/recorded and final mixes by Mario Quintero (AudioMQ) and mastering by Alan Douches (West West Side Music). Backing vocals on the single are by Violet Rouse.

Here’s the video for the track:

About The Quality of Mercury

Since you’re here …

… we have a small favour to ask. More people are reading Side-Line Magazine than ever but advertising revenues across the media are falling fast.

Side-Line’s independent journalism takes a lot of time, money and hard work to produce. But we do it because we want to push the artists we like and who are equally fighting to survive.

If everyone who reads our reporting, who likes it, helps fund it, our future would be much more secure. For as little as 5 US$, you can support Side-Line Magazine – and it only takes a minute. Thank you.
