Thornton Heath rapper Stormzy's debut single has not even hit the shelves yet.

But he got an early taste of the music world's big league last night when he took to the stage with Kanye West at the Brit Awards.

Stormzy joined fellow Croydon rappers Krept and Konan - and some fearsome-looking flamethrowers - amid a hoodie-clad mob bouncing behind West as he debuted new song All Day. 

London grime artists Skepta, Jammer and Novelist were also onstage. 

Stormzy's first single, Know Me From, will be released on March 8.
