No stranger to Greensboro Opera audiences, bass-baritone Donald Hartmann (Colline), is celebrating 44 years of singing. His professional career began in 1978 in Germany with the Stadttheater Regensburg and a debut with Greensboro Opera in 1979. He has been described as possessing a “big, rich voice with an amazing timbre” and “… his flair for comedic bel canto is major-league-worthy.” Having performed in over 160 operatic productions, in over 60 operas singing over 70 different roles, he is “one of the best character singers on any opera stage anywhere.” Notable performances include William Jennings Bryan in the 60th-anniversary production of Ballad Baby Doe for Central City Opera in Colorado and the Sacristan in Tosca in the historic reopening of New York City Opera’s return to Lincoln Center.
