Mezzanine was a renowned nightclub in the United Kingdom known for its vibrant atmosphere, eclectic programming, and influential role in the local and national music scene. Established in the early 2000s, Mezzanine quickly rose to prominence as a venue that embraced both established and emerging talent, catering to a diverse crowd that appreciated various genres, including electronic, indie, and live alternative acts. The club’s original site, most famously associated with the city of Bristol, became a crucial hub for the local creative community.

Mezzanine gained a reputation for its state-of-the-art sound system, immersive lighting, and commitment to pushing the boundaries of clubbing culture in the UK. Over its years of operation, the venue underwent several changes, with occasional restructuring of its physical layout to accommodate evolving trends in nightlife and audience demands. Despite periods of closure and uncertainty, Mezzanine managed to retain its status as a cultural touchstone for the city's music lovers, contributing significantly to the region’s nightlife and acting as a springboard for artists destined for wider acclaim.
