Who Am I (Katy B song)

"Who Am I" was written and produced by Katy herself, Craig David, Jr. Blender, Diplo and produced by Geneeus, Blender and Diplo. It's a midtempo R&B song, with smooth vocals delivered by Brien and David. Katy later admitted:

"[This song] was about my first boyfriend. I used to be in a band with him and when we broke up... I realized everyone I knew in London was in the band. I felt like I'd have to give up my band, my friends, my whole identity, start again from scratch. You don't just lose a person in a break-up. Others might lose their home, even their child and family, I think of people going through divorces when I sing it, too. It was originally a solo song, and I still don't really see it as me singing to Craig, we're the same person singing the same song."

"Who Am I" has received generally positive reviews from music critics and fans alike. Chantelle Fiddy of Mixmag gave the song 8 points out of 10, and commented: "Getting emotional with Craig David (who comes on here like Usher), this is a clever, Major Lazer-style take on the classic r’n’b duet". James Rettig of Stereogum described song as a "soulful jam" and Robin Murray of Clash described single as a "superstar clash" and praised Brien emotive vocals.

The music video for the song was shot in early February 2016 in Miami. It premiered on 23 February 2016. The clip shows Katy B and David performing the track amongst Miami's nighttime lights.

Katy and David performed track live for the first time on BBC Radio 1 Live Lounge on 14 March 2016 and later have done multiple gigs.
