Dennis Hanthorn, general director of Milwaukee’s Florentine Opera Company, is leaving to take the top job at Atlanta Opera. “Hanthorn said Atlanta offers ‘a bigger pond to play in.’ The metropolitan population is more than 4 million, compared with Milwaukee’s 1.3 million. The Atlanta Opera’s budget, Hanthorn said, was $6.8 million to Florentine’s $3.7 million. Atlanta staged four operas vs. the Florentine’s three. But the Atlanta Opera has a debt of about $1 million; the Florentine has been in the black for 11 years.”
