The message said: "We are still currently trying to determine the safety and whereabouts of all our band and crew. Our thoughts are with all of the people involved in this tragic situation."
The band were in Paris for the first stop of their 25-date tour of Europe and Scandinavia when the attacks occurred.
The coordinated terror attacks across Paris have left as many as 142 dead and paralysed the French capital with fear.
Around 112 were massacred at the alone, where terrorists held around 100 people hostage.
Paris police officials said security officials had launched an assault on the concert hall, killing at least two attackers. One described "carnage" inside the building, saying the attackers tossed explosives at the hostages.
In addition to the deaths at the concert hall, a police official said 11 people were killed in a Paris restaurant in the 10th arrondissement and other officials said at least three people died when bombs went off outside a stadium.
All of the officials spoke on condition of anonymity because they were not authorized to be publicly named in the quickly moving investigation.
There was no immediate claim of responsibility for the attacks, and no clear picture of how many attackers were involved and if any were on the run. Jihadists on Twitter immediately praised the attack and criticized France's military operations against Islamic State extremists.
Hollande, who had to be evacuated from the stadium when the bombs went off outside, said in a televised address that the nation would stand firm and united.
"This is a terrible ordeal that again assails us," he said. "We know where it comes from, who these criminals are, who these terrorists are."
