Cardiff’s nightlife is about to strike a new chord with the arrival of Piano Works, a high-energy, crowd-powered live music bar opening Friday 31st May on St Mary Street, taking over the former site of Dirty Martini.
Bringing a fresh twist to the city’s music scene, Piano Works Cardiff promises a non-stop, singalong experience where the audience decides the playlist. Every night, guests can scribble down their favourite songs and hand them over to the live band – no setlists, just back-to-back audience requests played by a talented roster of musicians and vocalists.
Already a hit in London, Piano Works is known for its vibrant atmosphere where live music meets party vibes. Think duelling pianos, sax solos, and hands-in-the-air singalongs to everything from Queen to Cardi B. Once the live music wraps up, late-night DJs will take over to keep the energy high into the early hours.

What to expect:
- Live musicians playing your song requests all night
- No setlist – the crowd controls the music
- DJs and dancefloor vibes after hours
- Food and drinks served until late
- A unique twist on Cardiff’s late-night offering
Whether you’re out with mates, on a date, or celebrating something big, Piano Works looks set to be one of the most fun new additions to Cardiff’s bar scene – interactive, unpredictable, and completely led by the crowd.
