Eminem 'Banging Out Tracks' on a New Album

It's the return of Slim Shady!

Ending a four-year break from music, rapper Eminem says he may release a new album this year.

"I'm concentrating on my own stuff right now – just banging out tracks," Eminem said in a recent interview on Sirius satellite radio station Shade 45.

The rapper, 35, will continue to produce for other artists on his label, Shady Records.

"The more I keep producing, the better it seems I get. I start knowing stuff, learning the boards like the back of my hands."

Eminem may have shelved his professional life since 2004’s Encore, but he's stored up a lot of personal material for his next album.

In 2005, the rapper entered rehab to treat a dependency on sleeping pills. In 2006, he re-married his ex-wife Kimberly Anne Scott, only to file for divorce three months later.

His mother, Debbie Nelson, who famously sued her son for $10 million over alleged slander in his debut The Slim Shady LP, has written a memoir titled, My Son Marshall, My Son Eminem, to be released in November.

"I do truly believe that Marshall will be back,” Nelson writes in the book.

"I'm sure he's biding his time, waiting for the right moment, and when he does return, he will be bigger and stronger and more successful than ever. I know my son, and he just doesn't give up that easily."
