SUSAN STAMBERG IS HOST Hour 1 Inventions of Bach: From a brand-new CD, pianist Evegeni Koroliov (ev-GAY-nee koh-ROHL-yawf) plays two of J.S. Bach's Two-Part Inventions, in C-minor and E-flat major. They're part of a series of keyboard pieces Bach wrote for his son Wilhelm Friedemann (VILL-helm FREE-deh-mahn) to practice. Grainger on the Shore: From MusicFest La Jolla (la HOY-yah), just north of San Diego, we'll hear Percy Grainger's folk song setting called "Molly on the Shore" performed by flutist Carol Wincenc (WIN-sents), violinist William Preucil (PROO-sil), violist Nokuthula Ngwenyama (noh-koo-TOO-lah EN-gwen-YAH-mah), and cellist Carter Brey (BRAY). The ensemble Piffaro (PIF-fah-roh) performs a selection of French Renaissance music. We'll hear "Donna Quando" (DOH-nah KWON-doh), "Ben venga Maggio" (ben VAIN-gah MAH-joh), and "Tentalora" (ten-tah-LOH-rah) by Jakob Arcadelt (YAH-kohb AR-kah-delt), and three anonymous works: "La Rocha el fuso" (lah ROH-chah del FOO-soh), "Il desparato" (eel des-pah-RAH-toh), and "La Lavandara" (lah lah-vahn-DAH-rah). Recorded in concert on July 8th at the Spoleto Festival in Spoleto, Italy. "Lark Ascending": In the novel "An Equal Music" by Vikram Seth (VEE-krahm SAIT), the central character falls head over heels in love with the violin after he hears the sublime "The Lark Ascending" by Ralph (RAIF) Vaughan Williams. We'll hear it performed by the Academy of St. Martin-in-the-fields, with Neville Marriner conducting. The violin soloist is Iona Brown. "An Equal Music": Susan talks with author Vikram Seth about his book "An Equal Music" (Vintage), which was recently released in paperback. It's a story of lost love and the inner workings of a string quartet. Vikram Seth reads selections from the novel and he'll explain what it was like to write about music from non-musician's point of view. From the companion CD to "An Equal Music," we'll hear music that's featured prominently in the book: the Minuet from Beethoven's rarely-heard String Quintet in C minor, Op. 104. The performers are violinists Maya Iwabuchi and Philipp Honore, violist Rachel Roberts and Clive Howard and cellist Sally Pendlebury. Hour 2 Seasonal Tchaikovsky: Tchaikovsky's piano cycle called "The Seasons" turns into a piano trio in the hands of the Bekova (beh-KOH-vah) Sisters--pianist Eleonora, violinist Elvira, and cellist Alfia. We'll hear them perform their own arrangement of "August" from a two-CD set released last summer. The Baltimore Symphony tackles a Russian masterpiece: the Symphony No. 6, the "Pathetique," by Peter Ilich Tchaikovsky. Music Director Yuri Temirkanov (YOO-ree tem-meer-KAH-nawf) conducts, from a June concert at Joseph Meyerhoff Hall in Baltimore. A Termirkanov encore: Yuri Temirkanov is principal guest conductor of the Danish National Radio Symphony Orchestra. In March he brought that ensemble to the Kennedy Center in Washington, DC, where they played this encore: "Tango Jalousie" (zhah-loh-ZEE) by 20th-century Danish composer Jacob Gade (YAH-kohb GAH-deh).
