MJ tribute concert planned in Vienna

Top artists such as Mary J. Blige, Akon and Chris Brown will sing some of Michael Jackson's greatest hits at a Sept. 26 global tribute in Vienna that also will feature a virtual duet between the King of Pop and one of his brothers, organizers said Tuesday.

But the much-anticipated lineup was a disappointment to a throng of reporters who had speculated that superstars such as Madonna would be part of the show to be staged in front of a 17th-century palace in the Austrian capital.

"Just hold your horses!" Jackson's brother Jermaine said at a packed news conference in Vienna's city hall, suggesting that some major names might still be added to the list.

Event promoter Georg Kindel said that up to 25 performers are expected to participate in concert that is being billed as the main global tribute for Jackson, who died June 25 in Los Angeles. More names will be unveiled later this week in London and Berlin, Kindel said.

Sister Sledge, Natalie Cole, Angela Bassett, and the Germany-based boy band US5 also are among the 13 artists confirmed so far, Jermaine Jackson said. In addition, Jackson's original band and dancers will take part.
