London grime MC Novelist delivered one of last year’s finest Appelsap shows, and this year we’re welcoming his former fellow Square member Elf Kid. Talent’s abundant in South London, as the 19-year-old rapper proved late last year with his excellent, self-explanatory break-out song ‘Golden Boy’, a tune that got a lot traction on both BBC 1xtra and Beats 1. You may also remember him jumping on Jamie xx’s rave-ready ‘Gosh’. Elf Kid, who’s in his first year at university, is playing both the BBC Introducing stage and Appelsap’s own SXSW party this spring, before heading to Amsterdam.
