The Reno Philharmonic opens its 38th season this weekend with a program of exotic music. Guest artists Sérgio and Odair Assad, pictured, will perform Joaquin Rodrigo’s Concierto Madrigal for Two Guitars. The Brazilian-born brothers are considered one of the most virtuosic guitar duos in the world, and many composers ranging from Astor Piazzolla to Francisco Mignone have written compositions for them. The Grammy award-winning guitarists have also worked with artists such as cellist Yo-Yo Ma and violinist Nadja Salerno-Sonnenberg. During the two concerts, the Reno Philharmonic Orchestra will also perform Paul Hindemith’s Symphonic Metamorphosis of Themes by Weber and Zoltán Kodály’s Háry János Suite . The concerts start at 4 p.m. Sept. 10 and 7:30 p.m. Sept. 12 at the Pioneer Center for the Performing Arts, 100 S. Virginia St. Tickets are $24-$58. Call 323-6393 or visit www.renophil.com.
