Several country stars took to social media over the weekend to react to the death of Southern Rock icon Gregg Allman on Saturday (5/27) at the age of 69. A message on The Allman BrothersBand’swebsite says Gregg passed away peacefully at his home in Savannah, Georgia. While no specific cause of death was immediately given, the message said that Allman had “struggled with many health issues over the past several years.”

Here’s how some of the country stars reacted to Allman’s death:

While playing his last show on the “Holdin’ My Own Tour” in Nashville on Saturday (5/27), Eric Church performed a rendition of The Allman Brother Band’s classic “Midnight Rider.” That performance can be seen here:

Keith Urban‏: My heart breaks today at the passing of soul brutha Gregg Allman. Blessings and peace to all the Allman family. – KU

Brad Paisley‏: What a legacy @GreggAllman leaves behind. Jam on in the great hereafter.

Jason Aldean: This one hurts a lot. This was one of my heroes. He made it seem possible for a kid to come out of Macon, Georgia, make a name for himself and make it in this business. He was such an inspiration to so many of us that tried so hard to imitate him but could just never quite do it the same. Thanks for the music and thanks for making me believe I could achieve my music dreams too. RIP Gregg Allman. https://www.instagram.com/p/BUnQp6XjhcU/
