Jeff Austin, the virtuoso mandolin player and singer known for his work with Nederland’s Yonder Mountain String Band and as a solo artist, died on Monday in Seattle, according to concert promoter AEG Presents Rocky Mountains.

No cause of death was given on Austin’s Facebook page, where updates on his health were posted over the weekend, but AEG Presents confirmed that the musician died after being put into a medically induced coma.

“It is with profound sadness that we announce the passing of a beloved family member, mandolinist, singer, songwriter and founder of The Jeff Austin Band and Yonder Mountain String Band,” said a statement posted Tuesday on Austin’s Facebook page. “He was son of Eileen Austin, husband to Devlyn and father to Lily Rose (12), Penelope (5) and Jude Patrick (2). He was a dear friend whose music touched the lives of so many, and will be sorely missed.”

A crowdfunding page has been set up to raise money to benefit Austin’s family via the Sweet Relief Musicians Fund.

Austin last week canceled a trio of live performances with the Jeff Austin Band at the ROMP Music Festival, Back Home Appalachian Arts & Music Festival and Smoky Run Music Festival, following an unspecified medical emergency.

On Saturday, his former bandmates dedicated a set to him at the Telluride Bluegrass Festival. Bassist Ben Kaufmann recounted on stage how Austin co-founded the popular Colorado band — one of the progressive bluegrass scene’s most successful — in 1998, according to jambase.com. Austin left to pursue a solo career in 2014.

The “emotional set” included performances from guests such as Tim O’Brien, Chris Daniels, Paul Hoffman of Greensky Bluegrass, Dave Bruzza and Anders Beck, jambase.com reported.

“We woke up today and the internet was on fire with rumors and speculation about our brother Jeff Austin,” Kaufmann reportedly said during the set. “And what we can say is that he is still with us. What is appropriate right now: if you’re a prayer, send prayers his way. If you’re a lover, send love his way. If you’re a healer, send energy his way. This is what we’re going to send his way.”

“Jeff Austin’s musical contribution to our community and his personal contribution to Colorado’s music community is gargantuan,” Don Strasburg, co-president and senior talent buyer at AEG Presents Rocky Mountains, told The Denver Post on Tuesday. “When you look through the social posts once his illness was announced, it was unbelievably common to see how many people were connected through his music and the music of Yonder Mountain String Band. It’s a tremendous loss for Colorado and the larger music community.”

Austin was born in Arlington Heights, Ill., in 1974 and met his future Yonder Mountain String Band mates after moving to Nederland.
