Eminem appeared on his Shade 45 Sirius channel in September 2008, saying: "Right now I'm kinda just concentrating on my own stuff, for right now and just banging out tracks and producing a lot of stuff. You know, the more I keep producing the better it seems like I get 'cause I just start knowing stuff." Interscope confirmed that a new album would be released in spring 2009. In December 2008, Eminem provided more details about the album, entitled Relapse: "Me and Dre are back in the lab like the old days, man. Dre will end up producing the majority of the tracks on 'Relapse'. We are up to our old mischievous ways ... let's just leave it at that."
