“I feel privileged, honored and humbled,” Wressell said about his directorial debut performing before royalty. “I only wish my mother was alive to see it. I’ll be thinking a lot about her that day.”The Swedish royalty will visit Minneapolis Oct. 6 to dedicate the new Nelson Cultural Center at the institute.

Wressell’s group, with a sound that has been described as both rich and beautiful, is one of three choruses performing for the royal occasion.
