The company that organized Woodstock 50 has just filed a lawsuit against the main investor, accusing the investor of sabotaging and money stealing.
Woodstock 50 claims in the suit ... Dentsu -- the chief investor -- blindsided them last week when it said they were pulling out, claiming safety concerns. Woodstock 50 says Dentsu was actually up to no good, allegedly draining the festival's bank account of $17.8 million.
Woodstock 50 says Dentsu then went on a campaign to sink any chance of the festival coming to life, contacting a number of agents of performers.
The suit claims Dentsu told various performers and agents Woodstock 50 was off and implied to them that they'd try to get them a spot at a 2020 Olympics event ... which Dentsu is sponsoring.
Woodstock 50 heads says the show will still go on, and it's suing to recover the money it claims Dentsu stole.
