Chris Brown, Mary J. Blige, Sister Sledge, and Natalie Cole will be among the performers in a Michael Jackson tribute concert later this month in Vienna, BBC News reports. Up to 25 acts will cover Jackson’s biggest hits, including “Billie Jean” and “Thriller.” More performers will be announced later this week for the concert, which is set for Vienna’s former imperial Schoenbrunn Palace on Sept. 26.
