Katy B, born Kathleen Anne Brien on May 8, 1989 in London, England, is a British singer, songwriter, and DJ known for her dynamic blend of electronic dance music, house, and R&B. Raised in the musical melting pot of Peckham, South London, Katy B attended the BRIT School, renowned for producing major UK talent. Early exposure to London’s vibrant clubscene and the city's underground radio culture shaped her distinctive sound and DIY approach.

She first gained prominence featuring on tracks by producers such as DJ NG and Magnetic Man, before signing with Rinse FM’s fledgling record label in 2010. Her debut album, "On a Mission" (2011), received critical and commercial acclaim, entering the UK Albums Chart at number two and earning a Mercury Prize nomination. Standout singles "Katy On a Mission," "Lights On," and "Broken Record" became club anthems, establishing her as a leading voice of UK dance music’s new generation.

Katy B’s soulful, nimble vocals over bass-heavy, genre-blurring production set her apart in the UK’s burgeoning electronic scene. Her second album, "Little Red" (2014), demonstrated greater musical maturity and featured collaborations with top producers including Jacques Greene, Route 94, and George FitzGerald. The lead single "Crying for No Reason" became her highest-charting solo single to date, highlighting her ability to balance introspective songwriting with dancefloor energy.

Katy B continued to experiment with genre fusion on subsequent EPs and collaborations, working with acts such as Four Tet, Craig David, Kaytranada, and Tinie Tempah. Her 2016 project "Honey" showcased her versatility, enlisting a wide array of producers and solidifying her reputation as a boundary-pushing artist in contemporary electronic music. Throughout her career, Katy B has maintained close ties to the club culture that inspired her, both as a vocalist and as a DJ, performing at clubs and festivals across Europe.

Her distinct blend of house, UK garage, dubstep, and pop has earned her a devoted following and critical respect for staying true to her roots while continuously evolving her sound.
