MJ Tribute Concert -- Peace Treaty Offered to Angry Fans

The people behind the upcoming Michael Jackson tribute concert want to make peace with the fans who have sworn to boycott the event ... by inviting them all to join in on a conference call to air out their grievances.

TMZ spoke to a rep for the concert who says they're inviting the leaders of several prominent fan groups to join them Wednesday for "an informative call to address some of the misinformation about the upcoming Michael Forever tribute."

For those unfamiliar, a TON of MJ fan groups banded together in anger -- after Jermaine and Randy Jackson claimed it would be "inappropriate" to support a concert "during the criminal trial surrounding Michael's death."

We're told event organizers are hoping the call with put "rumors and incorrect information to rest."
