New York City is the fifth character in this four-person musical about people who come to the city with hopes and dreams, some which are realized, some that are altered along the way. New Helvetia Theatre gathers some of its talented regulars to portray two couples—one romantic pairing, one a budding friendship, with New York both as a backdrop and as a central theme. Wonderful nuanced performances by Connor Mickiewicz (who also directs), Tristan Rumery, Kiera Anderson and Courney Glass, backed up by the talented pianist Erik Daniels. Th, F, 8pm; Sa 2 & 8pm;. Through 3/30. $30. New Helvetia Theatre, 1028 R St.; (916) 469-9850; www.newhelvetia.org.
