In spite of its name, the band does not play death metal, but bluesy rock. One of its founders, Jesse Hughes, has been described as "an unapologetic, Ted Nugent-esque Obama-basher who's a very vocal proponent of Ronald Reagan, Donald Trump, George W. Bush, and, most interestingly, the Second Amendment." Because of his pro-Israel views, it is possible the band's gig was chosen purposefully by the terrorists.
The venue itself was Jewish-owned for decades and had frequently been the target of anti-Semitic threats. It changed hands just two months before scores were murdered there.
