Fans and fellow artists around the world mourned the death of music legend David Bowie. Now, another great musician has left the earth. The Eagles founding member and guitarist Glen Frey passed away. He was 67 years old.

A statement is released on the band’s official website:

“It’s with the heaviest of hearts that we announce the passing of our comrade, Eagles founder, Glenn Frey, in New York City on Monday, January 18th, 2016. Glenn fought a courageous battle for the past several weeks but, sadly, succumbed to complications from Rheumatoid Arthritis, Acute Ulcerative Colitis and Pneumonia.”

“The Frey family would like to thank everyone who joined Glenn to fight this fight and hoped and prayed for his recovery. Words can neither describe our sorrow, nor our love and respect for all that he has given to us, his family, the music community & millions of fans worldwide.”

The band pulled out their Kennedy Center Honors appearance in Dec. 2015 due to an apparent relapse involving Frey’s intestinal issues, CNN reports.

Eagles’ band member Don Henley and the rest of the group are still in shock. However, Henley said that he was grateful meeting Frey.

“I’m not sure I believe in fate, but I know that crossing paths with Glenn Lewis Frey in 1970 changed my life forever, and it eventually had an impact on the lives of millions of other people all over the planet,” the musician said.

“But, I will be grateful, every day, that he was in my life. Rest in peace, my brother. You did what you set out to do, and then some,” he added.

Meanwhile, musicians from different genres posted their tribute via Twitter:

Frey co-founded Eagles in 1971 with Don Henley, Bernie Leadon and Randy Meisner. According to the BBC, Eagles was one of the “great forces of 70’s rock” along Led Zeppelin and Fleetwood Mac.

The band had more than 150 million album sales worldwide. Their famous hits include the all-time classic “Hotel California” and “I Can’t Tell You Why.”
