You produced four tracks on Slime Season 3: "Digits," "Memo," "Worth It," and "Tattoos." How did those four songs end up on the tape?

I did four tracks on there out of eight. There's a lot of tracks that me and Thug did. We wanted to give them that boom, that fire, so we gave them the club music. Those was one of the top three, four club music tracks that we have. The other ones that we have, we're gonna save for the album. The ones we got for [Hy!£UN35] are truly amazing.

So these are tracks from the vault, not new tracks made specifically for the tape?

All the tracks that are on there are two years old. I think we made "Digits," "Memo," and "Tattoos and Piercings" all in one day. We was high as hell and we was just turning up and making music like we always do and Thug pulled up. There was a lot of people there, it was me, Alex [Tumay], Duke was there, and his sisters Dora and Dolly where there.

That’s a productive day. What is your workflow like when you are working with Thug?

Me and Thug's chemistry is so good, it's immediate every time. I always make music in front of him—on the spot, from scratch. When I play a few melodies, he's like, "That's it right there, finish that." And I'll be like, "You sure?" And he'll be like, "That's the melody right there." So I lay down the melody, then I put two or three more sounds to it, and then I'll put it in ProTools and he just goes in and rips it from there. He does what he does, and then he's like, "Okay, I did my part, London, I want you to tweak it." So I finish it up. I'll make sure it's complete—this breakdown is for this part right here, this is for that section, the intro need to start like this. We just play around with it until we know it's a hit.
