Jason Isbell's ticket page on the Newhaven host has no upcoming dates. The room that still does is Hartford Stage, with 145 dated rows through March 21, 2027.
Nights already posted include Dracula - The Musical on October 22, 2026; Dracula - The Musical on October 23, 2026; Dracula - The Musical on October 24, 2026. That mix is why the venue page still works as a Newhaven indoor link after a single performer page dies.
Local listings and the venue ticket page are the current dated sources for this replacement; the expired performer URL is the one that went blank.
The old link is the one that expired. Hartford Stage is the unused venue with a last date of March 21, 2027.
The current list is at Hartford Stage tickets.
