Mary J. Blige to lead Jackson tribute in Vienna

VIENNA, Sept 8 (Reuters) - Artists including R&B stars Mary J. Blige, Akon and Chris Brown as well as veterans Natalie Cole and Sister Sledge will perform at the Vienna Michael Jackson tribute concert later this month, organisers said on Tuesday.

Thirteen artists so far confirmed to perform at the concert, set in front of Vienna's Schoenbrunn castle on Sept. 26, Michael's brother Jermaine Jackson and producer Georg Kindel told reporters at a news conference in Vienna.

They expect a total of 20 to 25 names, more of which will be unveiled at separate news conferences in London and Berlin later this week, they said. (Reporting by Petra Spescha; writing by Boris Groendahl, editing by Paul Casciato)
