'Rigoletto' in Duluth

First produced in 1851, Giuseppe Verdi's opera "Rigoletto" is a masterpiece of the composer's white-hot maturity, and has continued to grip audiences with its shadowy fable of sexual predation, betrayal and murderous intrigue. Lyric Opera of the North presents two performances of Verdi's drama, with singer John Pierce as the court jester whose plot to assassinate his daughter's aristocratic seducer goes tragically off-kilter. Tenor John Cudia gets the best-known aria, though — the Duke's braggadocious "La donna è mobile" ("Women are fickle things"). (7:30 p.m. Thu. & Sat.; Marshall Performing Arts Center, Duluth; $12-$57, 1-218-464-0922 or loonopera.org)

Celebrating the harp

The American Harp Society is in Minnesota for its summer gathering. The conference kicks off Sunday with a pair of public concerts showcasing an instrument too often tucked away on the periphery of symphony orchestras. The first concert features soloist Katherine Siochi, gold medal winner at last year's triennial USA International Harp Competition, who plays pieces by Debussy, Chopin, Ravel and Elias Parish-Alvars. A second evening recital puts Minnesota vocalists and instrumentalists in the spotlight with a program featuring music by local composers Dominick Argento and Stephen Paulus. (2:30 p.m. & 7:30 p.m. Sun.; Boe Chapel, St. Olaf College, Northfield; $12, ahssummerinstitute.org)

(7:30 p.m. Thu., 3:30 p.m. Sat., 2 p.m. & 5:30 p.m. Sun.; Raspberry Island, St. Paul; free, onevoicemn.net)

Fresh folk music

(7:30 p.m. Sat., Studio Z, St. Paul; $8-$15, studiozstpaul.com)
