Barto: "We have a good relationship with Wayne's engineer, KY. He mentioned that Wayne was doing a rock album. We didn't know if it was going to be rock guitars over rap beats or whatever. He was like, 'Nah, straight rock.' So, we were like, 'Let's do it.' When we got the call we basically got right to work. We were all picking up guitars and trying to rock out, experimenting with different genres. You can tell 'Knock Out' has a very early-2000s punk sound to it.

"We weren't bored with hip-hop because everything that we had been doing had been pretty exiting. However, we are always hungry for more. I believe we are pretty talented producers of music in general, so people might box us in because they have only heard within a certain scope of what we can do. The opportunity to have placements on a rock album was too irresistible.

"I don't believe the idea of Wayne doing a rock album was initially welcome for the most part. It's funny how people just don't have faith in you. The same people who didn't have faith and were like, 'Wayne's on a rock album? Come on!' And I'm like, 'Yeah, we're going to be on it actually.' And I get a call or a text message from the same people talking about how they were fucking with the album. It's crazy. We were on board automatically for it as soon as we heard about it. I don't care what people are going to think. Let's do it, let's make it hot. Let's contribute to the album being a success. It's just part of having a vision for it and having faith."
