Eminem Wins Pair Of Detroit Music Awards

Rapper performs at ceremony with his group, D-12.

Eminem added a few more accolades to his collection Friday night, winning both categories he was nominated in at the 11th annual Detroit Music Awards.

Slim Shady was at the ceremony and performed a medley of songs with his group, D-12, but did not take the stage to accept his awards, according to organizers.

His controversial, yet acclaimed, The Marshall Mathers LP won Outstanding National Album, beating out a diverse bunch of records by Kid Rock, Madonna, Robert Bradley's Blackwater Surprise, the Suicide Machines and Uncle Kracker.

"The Real Slim Shady" topped Kid Rock's "American Bad Ass," Robert Bradley's "Higher" (which features Kid Rock), Uncle Kracker's "Yeah, Yeah, Yeah," the Suicide Machines' "Sometimes I Don't Mind" and the Workhorse Movement's "Keep the Sabbath Dream Alive" for Outstanding National Single.

Kid Rock was also in attendance at the event, which was staged at Detroit's State Theatre.

More than 70 awards were handed out at the ceremony, including Distinguished Achievement awards to Motown songwriting great Barrett Strong ("I Heard It Through the Grapevine," "Papa Was a Rolling Stone") and late Blues legend Willie D. Warren.

Eminem's The Slim Shady LP won Outstanding National Album at last year's Detroit Music Awards, though the rapper lost the Outstanding National Single award to Kid Rock's "Cowboy."
