The techno DJ behind the 2006 single “Be Divine,” which featured Adele, was Ricsta.
“Be Divine” was released on 23 January 2006 as a Ricsta track featuring Adele. It predates Adele’s solo debut and is generally identified as her first officially released vocal credit. The track appeared as a club-oriented single and was issued in several remixed versions.
At the time, Adele was still developing her career and had not yet released *19*. Her contribution to “Be Divine” is therefore easy to overlook, especially because the song was not a mainstream chart hit and is absent from most casual summaries of her discography.
The question asks for the DJ or principal artist, not the featured singer. Adele supplied vocals, while Ricsta was credited as the artist responsible for the record. Mark Ronson, Calvin Harris and Fatboy Slim are unrelated names from the broader electronic and pop landscape.
