Legendary performer Gregg Allman has cancelled all of his upcoming tour dates. “It has been determined that Gregg will not be touring in 2017. For those of you who purchased tickets for shows in June, contact the ticket outlet from where you purchased the tickets for a refund,” reads a note on GreggAllman.com.

Gregg has been battling health issues that have only allowed him to perform a few times since last summer. In November, Allman canceled all dates through the beginning of 2017. Gregg was previously scheduled to return to the road in June for a series of shows that included a July residency at City Winery in New York City.

No further details are available regarding Gregg’s decision to cancel all shows.
