In an interview with Vice.com in Los Angeles, they described their horror as they watched terrorists shooting indiscriminately into the crowd, many of whom initially mistook the bursts of automatic gunfire as part of the show.
U2 helped them in the aftermath of the attacks, buying them mobile phones to replace the ones they abandoned during the chaos at the Bataclan, and offering them the use of their plane.
Members of U2 were among the first to visit the Bataclan to pay tribute to the victims as the Irish band was in Paris preparing for two concerts that weekend, which were postponed after the attacks. They are finally playing them tonight and tomorrow.
U2 has often explored the theme of terrorism. A simulated bomb has gone off half-way through its recent shows during the song Raised by Wolves, which commemorates 1974 car bombings in Dublin. "Blood in the house, blood on the street," Bono sings. "The worst things in the world are justified by belief."
Jesse Hughes, the lead singer of Eagles of Death Metal, is a contradictory figure. A flamboyant rock musician and reformed drug addict, he is also an ordained priest and a Republican supporter who has boasted about how many guns he owns and his opposition to gun control. He will be joined on stage by his childhood friend and the co-founder of the band, Josh Homme, who rarely tours and was not in Paris on the night of the attacks.
There will be unprecedented security at the concerts. France remains in a state of emergency with thousands of police and soldiers guarding the streets of Paris.
A 25-year-old man named as Mohamed S, was expected to be charged with involvement in a terrorist conspiracy yesterday over his alleged role in providing a safe house for the alleged ringleader of the attacks, Abdelhamid Abaaoud.
