“Who” is the eighth track of Project E.T. Esco Terrestrial this song features Young Thug and Future who have had some problems in the past. Although seeing this feature, the two Atlanta trap rappers may’ve buried their conflict.

Thug said this on Twitter in November 2015.

I have nun in the world against future I listen to his music His music makes me happy and I hope he continues to bless me and others with it.

Their last collaboration together was set up by Metro Boomin who featured both artists on his song, “Chanel Vintage” back in 2014. They also collabed together on “California Rari”.

The mellow, yet upbeat production by Metro Boomin and DJ Esco allows Future to spit his braggadocios bars yet blend in with Thug’s crooning voice.
