Country musician Tommy Alverson has died, according to social media posts from family and friends. Alverson’s wife, Amy, confirmed the news on Thursday.

Alverson’s age and cause of death were not disclosed, but the Texas music legend recently underwent immunotherapy treatments. The American Cancer Society describes these kinds of treatments as attempts to “boost or change how the immune system works so it can find and attack cancer cells.”

“Tommy left us this morning at 7:26 am surrounded by most of his family in Ft Worth Texas,” an official announcment read, as captured by Galleywinter and Texas Music Daily. “Please be respectful and give the family some time. Focus on all of the friends, memories and great times that Tommy is responsible for bringing together.”
