With scads of talent to perform onstage and in the orchestra pit, productions at the University of Cincinnati’s College-Conservatory of Music can authentically replicate productions from the Golden Age of Musicals. The October 2018 staging of Guys and Dolls — which marked the 50th anniversary of the musical theater program’s establishment (the first in the United States) — had a cast of around four dozen for each performance, accompanied by an orchestra with more than 25 musicians. That’s what Broadway used to pull off — but not in the 21st century. The show was a serious blast from the past. Cincinnati’s College-Conservatory of Music, 290 CCM Blvd., Clifton, ccm.uc.edu.
