Organizers say Mary J. Blige, Natalie Cole and Sister Sledge are among 13 artists who will headline a Sept. 26 Michael Jackson tribute concert in Vienna.
Jackson's brother Jermaine says up to 25 performers are expected to perform outside a 17th-century palace in the Austrian capital. He says more names will be unveiled at news conferences later this week in London and Berlin.
Jackson and event promoter Georg Kindel told reporters Tuesday that Chris Brown and German-based boy band US5 also will perform some of Jackson's greatest hits at the concert.
Organizers are billing the event as the main global tribute to Jackson, who died June 25 in Los Angeles.
Kindel says Jackson's family and children will be in Vienna, and 65,000 fans are expected to attend.
