A Michael Jackson tribute concert which was scrapped in Vienna and moved to London after top acts dropped out has been canceled after the event's organizer closed down, the company's liquidator said on Friday.

Organizers, led by Michael's brother Jermaine Jackson, canceled the Vienna concert in September after struggling to get stars to perform at short notice in the small Alpine nation.

They had planned a replacement concert in London in summer 2010 but this has also been scrapped.

Martin Schneider, liquidator for the organizers, told Reuters: The company cannot sign any new contracts and will certainly not plan any new events.

Event organizer World Awards Media GmbH decided to close on November 30, the company's liquidator said in an e-mailed statement. World Awards Media and its previous owner directed all queries to its liquidator.

Ticket sales for the Vienna tribute stagnated after billed acts such as R&B stars Mary J. Blige and Chris Brown and veteran singer Natalie Cole started to back away from the concert which would have taken place at a 17th century palace.

Organizers blamed Austrian media, saying they treated the line-up as B-List artists and sullied the memory of Jackson.

The singer died in June, aged 50, from an overdose of powerful medications. His 1982 Thriller is the highest-selling album of all time.
