Life is lovely featured worldwide acts like Lorde, Muse, Gorillaz, Chance the Rapper and The xx.
Investigators are exploring whether Las Vegas suspected shooter Stephen Paddock sought a hotel room overlooking another outdoor concert in Las Vegas in late September that featured Chance the Rapper and Lorde, two sources told ABC News.
"We have information that he may have attended 'Life is attractive, ' but we haven't confirmed it yet", the sheriff said.
They apparently suggested Paddock may have lost his nerve at the earlier festival, and instead turned his attention to the Route 91 Harvest Festival, where he undertook the most deadly mass shooting in modern USA history.
On Monday, the world was rocked by the news of a shooting in Las Vegas that has, at the time of writing, left 59 people dead (including the perpetrator), and a further 530 injured.
The Daily Beast's source suggested that Paddock either lost his nerve or changed his plans to focus on the Route 91 Harvest festival instead. "As you know this is an ongoing investigation", Warren said. Through a broken window in his hotel room, the 64-year-old shot into a crowd of about 22,000 concertgoers during the performance of the Route 91 Harvest festival's headliner, Jason Aldean.
The official also confirmed that housekeeping was asked not to visit Paddock's room at Mandalay Bay for at least part of his stay.
The head of the festival, Justin Weninger, said in a statement, "The Life is Beautiful Festival family is devastated by the horrific events that took place on October 1 in our hometown of Las Vegas".
