In the wee hours of Sunday morning, a lone gunman entered Pulse—a gay club in Orlando, Fla.—with an AR-15 rifle, opened fire, and killed 49 people, injuring 53 more, before being shot and killed by a SWAT team.

In the hours following the shooting, which would later be categorized as the worst mass shooting in America’s modern history, it would be discovered that the shooter’s name was Omar Mateen, and he had declared allegiance to the Islamic State via a 911 call the morning of the shooting. Later, IS would take responsibility for the attack.

The event prompted social media reaction among many groups. Country musicians, long-known for their ties to American culture and patriotism, were no different.

Several artists expressed their condolences on Twitter and Facebook on Sunday and into the following day on Monday.

Crying as I read about Orlando. I can't believe it. I don't understand. And especially at such a happy place!? Feeling sick.

Tweeting about this kind of tragedy feels so insignificant. But let's all pray for Orlando FL today. And the world. I'm in disbelief.

Saddened by the news this morning. Such a shame. My thoughts and prayers go out to those affected in Orlando.

— Luke Bryan (@LukeBryanOnline) June 12, 2016

A great fear is that these things will be able to continue to happen so much that we become desensitized to it. Orlando, I am so sorry.

However, some artists entered into the political ring, expressing more than “thoughts and prayers” for the victims and their families.

50 people dead in Orlando
Terrorism has come to the streets of America
and if you're depending on Obama forget it
Lock and load my brothers

— Charlie Daniels (@CharlieDaniels) June 12, 2016

Islamic Terrorism slaughtering American citizens and president who won't even say the words.
How about putting America first for once Obama

— Charlie Daniels (@CharlieDaniels) June 12, 2016

failing in acquiring guns fault lies in the federal system. This guy should never have got one.he was known to sympathize with radical Islam

— Charlie Daniels (@CharlieDaniels) June 12, 2016

Defeating terrorism with political correctness is like attacking a three alarm fire with a bucket of high test gasoline

— Charlie Daniels (@CharlieDaniels) June 12, 2016

Why does our president always make excuses when a simple. "WE'RE GETTING READY TO KICK SOME MAJOR BUTT" would be appropriate?

— Charlie Daniels (@CharlieDaniels) June 13, 2016

Others, like country DJ Bobby Bones, started an effort to begin the healing, starting the hashtag #musicistherapy. He had several country artists play songs live on his show Monday morning as a tribute to the lives lost in the shooting.

we're going to try to do a good show for you today.
lots of artists stopping by to play as their message of love. #musicistherapy
