according to focus
As he awaits the album's online debut, Focus is keeping busy working on tracks for the upcoming, but tightly under-wraps, first album in nearly four years from Aftermath kingpin Marshall Mathers. "Marshall's album is coming out soon, and we just did a couple tracks together, and we've done a lot of writing together," he said. "I make my beats and send them out to him." But other than confirming the existence of a new album from Eminem, Focus wouldn't divulge much else about the sound or the style of the project.
He was also tight-lipped about his work on Dre's long-gestating final album Detox which Focus said should definitely be coming out this year. "We're heavy into Detox now. I'm trying to get some tracks on there and give him whole songs so he can keep everything moving. Detox is coming this year. I know that's what he's been working very hard on. I want my tracks to be as big as Dre's name and legend are."
