Dierks Bentley is one of many who were badly shaken by the recent massacre at Las Vegas's Route 91 Harvest Festival, which has been now named largest mass shooting in American history, with 59 deaths and more than 500 injured.

"I'm having a hard time even physically moving right now. I had to take Twitter off my phone because I've just been looking at it for two days straight," he told the Hollywood Reporter. "It's just the heaviest, darkest thing I can remember since 9/11."

Bentley, unsurprisingly, is especially distraught over the tragedy due to the fact it hit the country music community, which he acknowledged is a close-knit group.

"Those fans are all family to us. It's a community like no other, and I'm sure I know some people that were killed or wounded. We see a lot of the same faces on the road. It's a really tight group," he noted. "The boundaries between the audience and the stage are thin, metaphorically, in country music."

Bentley is currently at home in Nashville with his family, and said on Wednesday he had his "first smile in two days" giving blood to the Red Cross with other donors to help out victims of the tragedy.
