Last month, Rochester welcomed composer Steve Reich. This week, composer-pianist John Musto comes to town as part of a five-day residency co-hosted by Nazareth College and Rochester Lyric Opera. In a visit that includes a composer's forum on Thursday, April 21, at 4 p.m. on the Nazareth campus (free and open to the public), the residency culminates in the staging of Musto's opera "Bastianello" on Saturday, April 23, at The Lyric Theatre. With an English-language libretto by Mark Campbell, this one-act comic opera tells the story of 18th-century newlyweds Amadora and Luciano — performed by mezzo-soprano Katie Hannigan and bass Zachary James, respectively. The groom jaunts off on his wedding night only to find six people as silly and unwise as his wife and in-laws. The production is stage directed by J.J. Hudson, and Jared Chase will conduct.
