Dr. Dre debuts "Detox" in Dr Pepper ad

Rap artist Dr. Dre speaks during the 2006 Los Angeles Chapter of the Recording Academy's annual ceremony to honor extraordinary artists in Los Angeles, California June 8, 2006.

NEW YORK (Billboard) - It may just be a few seconds of music, but Dr. Dre fans will remember the new Dr Pepper ad as the spot where they heard the first officially released beats from his much-delayed album "Detox."

The L.A.-based hip-hop producer appears in the latest installment of an ad campaign entitled "Trust Me, I'm a Doctor," and teases the song "S--t Popped Off," from the long-awaited album, slated for a late 2009 release on Aftermath/Interscope. The commercial will begin airing Monday (June 1).

"Scientific tests prove when you drink Dr Pepper slow, the 23 flavors taste even better. For me, slow always produces a hit," Dr. Dre says in the commercial, before stepping behind a DJ booth, putting on a pair of his own signature "Beats" headphones and slowing down the sped-up techno song that's playing by placing a can of Dr Pepper over the record. The new track comes on, the party goes wild, and Dre states, "Slower is better -- trust me, I'm a doctor."

Other spots in the campaign feature hoops icon Julius Erving (a.k.a. "Dr. J"), Kelsey Grammer (a.k.a. "Dr. Frasier Crane") and Gene Simmons (a.k.a. "Doctor Love").

Guest appearances from Jay-Z, Lil Wayne, Nas, Eminem and 50 Cent, among others, are on tap for "Detox."

Dre's last album, 1999's "Dr. Dre 2001," has sold 7.2 million copies in the United States, according to Nielsen SoundScan.
