Harlem rap crew A$AP Mob invaded Coachella Music Festival on Friday (April 11). On a sweltering hot afternoon, trap leader A$AP Ferg introduced fans to his motley crew of rhymers.

But before he did that, Fergenstein performed a few songs from his latest album 'Trap Lord,' including 'Shabba' and 'Cocaine Castle.'

Ferg, who was dressed in all white except for burgundy sneakers on his feet, stepped aside to let fellow Mob members A$AP Nast and A$AP Twelvy perform tracks from their upcoming compilation album, 'L.O.R.D.'

The highlight of the show happened midway when A$AP Rocky graced the stage to perform a new song.

The unidentified tune boasted a menacing beat as Dat Pretty MF recited gritty rhymes about keeping it real for the streets.

"When the real n----s die / F--- n----s will multiply," went the chorus.

A$AP Ferg closed his set out with rollicking renditions of 'Let it Go' and 'Work,' respectively.

Watch A$AP Mob keep it trill at Coachella.
