Kendrick Lamar, Jay Rock, ScHoolboy Q and Ab-Soul are Black Hippy. Their collaborations have garnered serious love from fans as well as critical acclaim, but we still haven't received a full-fledged group album. Why? Well, we asked Jay Rock.

"Everybody's just working," Rock told MTV News. "Everybody is focused on their individual thing. When we do come together to make records, it's easy because we've had that chemistry since day one. We all shared the same studio for years so that sh-t is automatic."

The group came together for "Vice City," the latest single off Rock's 90059. It's an early fan favorite and Rock thinks he knows why it's been so well received.

"Everybody was like, 'Damn, this song is so dope,' because we ain't had fun like that in a long time," he explained. "Everybody is busy working. ScHoolboy Q's on the road, Soul's on the road, Dot's on the road. But when we do get time to do something, we do it and we do it right."

The song -- a call back to tracks like "Say Wassup" and "Black Lip Bastard (Remix)" -- also makes us wonder if the group will ever clear the schedule to make the joint project that TDE fans are waiting for. We asked Rock if he ever sees that happening.

"Of course," he said. "I've heard talks that all of us are supposed to do a tour together. So, most likely we're gonna have a studio on the bus, so you never know."

Back in 2013, Ab-Soul called a Black Hippy LP Detox 2, a nod to a highly anticipated Dr. Dre album that the world will probably never get.

Last year, Kendrick told us we might be seeing something in the future. Perhaps he was referring to "Vice City?" Now, with Jay Rock's admission that a Black Hippy tour might be coming, it looks like huge progress is being made. Still, time will tell if the world will ever really get that project.
