Kanye West debuted his new single "All Day" in true mob fashion this week. Yeezus took over the stage of the 2015 BRIT Awards surrounded by more than a dozen men shrouded in black hoodies -- and, of course, most of them were fellow artists.

In addition to Theophilus London and Allan Kingdom (who are both featured on the track) and Vic Mensa (who's featured on "Wolves"), 'Ye was also surrounded by a few well-known U.K. grime rappers.

Some of them are newcomers, while others have been working their way up through the underground scene for years.
