With four nominations each, Amy Winehouse and Dizzee Rascal lead the field for the Music of Black Origin (MOBO) Awards, to be held Sept. 19 at London's O2 Arena. BBC1 will broadcast it two days later.

Winehouse is up for best U.K. female, best song for "Rehab" (Island), best video for "Back to Black" and best R&B honors. Rascal is a contender in the categories for best U.K. male, best song and video for "Sirens" (XL), and best hip-hop.

Meanwhile, Akon, P. Diddy, Kanye West, Rihanna and T.I. will go head-to-head for the best international award.

The public are invited to cast votes via the MOBO Web site. Hosting the event will be Shaggy, who was on hand to unveil the nominations last night (Aug. 22) during a party at the Movida club in central London.

Arranged by the MOBO Organization, the 12th annual MOBO Awards will be the first industry ceremony held at the state-of-the-art Greenwich venue. Owned and operated by the Anschutz Entertainment Group (AEG), the O2 arena opened for business on July 7 on the site of the maligned Millennium Dome.

As previously reported, the MOBO Organization are establishing the MOBO Foundation, which intends to address the problems that people from ethnic-minority communities face when seeking employment or setting up business in the British music industry.
