Roc Nation rapper J. Cole recently talked about the popularity of hip-hop artists coming together to work on joint efforts and why those collaborative efforts hardly ever materialize.

Despite strong performances like 2011’s Watch the Throne and Bad Meets Evil, Cole cited the lack of will power and mutual efforts keeps those artists from dropping even more joint LPs.

Cole convinced us with his confidence, but he did say that he now realizes why the business makes it difficult for two artists, from different labels to collaborate on a single project. Artists like Nas and AZ, MF Doom and Ghostface Killah, and Fabolous and Ne-Yo have all been conceptualized, but none of them have yet to materialize. “Now I see why those joints don’t happen, but it’s a different thing when you got will and both your minds are set on it; it should happen,” he said. “But I can see why that sh– is hard, like all those f—in’ joints that were supposed to happen back in the days.” (MTV)

Last year, Cole hinted at plans to work on a joint effort alongside West Coast rapper Kendrick Lamar.

“I just started working with Kendrick the other day,” Cole said. “We got it in, finally, again.” After confirming the project will be an album, not a mixtape, he said the pair left the session with four of five songs together. “We actually worked, bouncing ideas, which was great,” Cole said. “The vibe was so good that it was like, ‘Man, that’s absolutely gonna happen.'” (Fay Observer)

Recently, New York rap veteran AZ talked to SOHH about wanting to finally turn out some records with fellow Big Apple emcee Nas.

“As far as Nas, I know he was working on his album and he was moving around so much and I was moving around so much [last summer], I still tour and all that, it was more or less I had to wait for the right time to put something out. So in the meantime, between time, I just decided to put something out and get it out there. Hopefully that collaboration between me and Nas will pop off but my album is halfway done and I’m going to continue to hopefully put out music every month.” (SOHH)

A couple years ago, Grammy-winning rapper Lupe Fiasco said fans should not hold their breath for a collaborative effort with himself, Kanye West and Pharrell Williams.

“Um, probably not. I don’t foresee it. I don’t know,” Fiasco said when asked about the LP’s status. “Everybody has their different approaches. Do you want a CRS album or do you want a ‘Friend of the People’ mixtape or do you want a ‘Food and Liquor 2’ or do you want… It’s like, you know, you can’t do all of it. And then with CRS I have to get Pharrell on the same page and get Kanye on the same page – is it something that we even still want to do, you know? It was something that we maybe thought about doing 3 or 4 years ago. 3 or 4 years later, is that something that we still want to do? … It ain’t on me, it ain’t on Lupe — There’s three other people that’s involved; three different record labels; three different kinds of systems and management and all this other kind of stuff involved. So, creatively I’m always down to collaborate but, this particular thing, I don’t know.” (All Hip Hop)
