Sugarland sued
The country duo Sugarland is being sued by dozens of people who claim they were injured in a devastating stage collapse at a concert in Indiana earlier this year ... all because the band allegedly failed to cancel the show when they KNEW the weather was getting bad.

More than 40 people -- including the estates of people who died in the accident -- filed the suit against the band in Indiana ... claiming the members of Sugarland had the authority to cancel the show because of bad weather.

According to the docs, Sugarland "failed" to call it off ... putting the fans in grave danger.

Moments before the performance on August 13, powerful winds blew in and knocked over the stage -- killing 7 people and injuring more than 45.

Sugarland isn't the only defendant in the lawsuit -- the alleged victims are also demanding unspecified damages from concert promoter Live Nation, ESG Security and the stagehands’ union.
