Jay-Z and Kanye West plan 2nd album

Producer Mike Dean promised: "It's not started yet, but it's coming."

'Found our zone'

In December, Jay admitted he was keen to record with Kanye again, but only after they'd each returned to their solo projects.

He said: "It depends on how this thing finishes up. We - I say 'we' because I'm in 'Throne' mode - we're in a great place creatively. You might see a Jay, then Kanye and a 'Throne' album next year. 

"You know, we're really in a great place creatively. We really found our zone."

The pair's sound engineer Young Guru recently predicted another collaboration would happen, but he anticipated it being in 2013.

Referring to Kanye's forthcoming album with artists from his G.O.O.D. Music label, he said: "The way I would like it to go, I would like Kanye to do the G.O.O.D. Music album and Jay-Z to do a solo album, then they go out and tour then next year, or the end of the year, we get Watch the Throne 2."
