Playboi Carti and Awful Records' Ethereal reconnect on "Lemme Know." The slow burner finds Carti and Ethereal talking smack about what they are able to do in a bunch of different situations.

"Lemme know what's up, I let you know what's up, yea/I'mma bag it up, she goin' back it up, yea/I just live it up, we goin' live it up/I'mma air it up, no we can't put it up," raps Carti on the hook

Ethereal and Playboi Carti haven't really made music with each other for a while now so this is probably an old song that's just been released. Cash Carti used to run with Awful Records a few years ago but ever since last year he's been at A$AP Rocky and A$AP Mob's side while ascending to be one of the hottest young MCs in hip-hop right now. Rocky congratulated Carti on his Intercrope Records deal back in September, days after Carti performed one of his biggest tracks, “What” at the G.O.O.D. Music pop-up shop in NYC.

The two Atlanta natives previously made records such as "Beef," "Pump Fake" and "IKnowuKnow." Cartii recently released “Red Lean” last month. Ethereal released his collaborative Slum Beautiful EP with fellow Awful spitta Archibald SLIM.
