Pro Uno Channels Retro Love with “Four Letter Word”

Do they still craft tunes that sound like that? Pro Uno absolutely does—and somehow makes retro nostalgia sound even better than we remembered.

"Four letter word" offers a fresh spin on classic vibes. It’s essentially a love song that drifts on the evening breeze, floating right through your open window.

The track’s funky and soulful, you know? There’s this liquid groove woven into the lyrics that gives it a distinctive indie-pop finish.

What really sets this apart is the full band arrangement. We’re talking strings, horns, flute—the whole nine yards. But here’s the kicker: those congas that punctuate the rhythm throughout? Pure genius.

Hailing from Australia, Pro Uno is led by musician Liam Stacey from The Regime. Definitely worth keeping tabs on this project via the links below for any upcoming releases.
