Even the Artistic Director and Founder of Conspirare, Craig Hella Johnson, finds it hard to believe that the choral ensemble is 30 years old. He’s developed a fall season that’s kind of eclectic with a nod to the past and an eye on the future. One choral group is being invited back for the holiday program. It’s Isaac Cates & Ordained who will, says Johnson, bridge the past with the future.
