In 10 seasons, Portland SummerFest has presented some of the world's best operas with its free “Opera in the Park” series. The list includes “Carmen,” “The Barber of Seville,” “La Boheme” and “Die Fledermaus.”

Now, artistic director and conductor Keith Clark is back with an all-star cast of performers. This year's opera, Giuseppe Verdi's “Otello,” will run Aug. 2 at the Washington Park Amphitheater and Aug. 4 at Concordia University's Campus Green in Portland.

The opera is presented in concert format with a full orchestra and lively narration. The atmosphere is informal, and families are welcome. Since 2003, the series has brought free opera to more than 30,000 Oregonians, according to a news release.

Verdi's “Otello” is based on William Shakespeare's play “Othello.” The four-act opera was first performed at the Teatro alla Scala on Feb. 5, 1887, according to the Portland SummerFest's website.

This production features internationally known tenor Allan Glassman as Otello and The Metropolitan Opera's baritone Richard Zeller as Jago and soprano Angela Meade as Desdemona.

The free performances begin at 6 p.m., and picnics are welcome. For more information, visit
