The first installment of the Los Angeles Philharmonic’s ”Filmharmonic” project, a mini-festival celebrating Hungarian composer Gyorgy Ligeti’s 75th birthday, and performances of several works by American composers are some of the highlights of the Philharmonic’s 1997-98 season.”Filmharmonic,” an ongoing program of newly commissioned multimedia works involving composers and film-makers, will be launched with ”Tales From 1,001 Nights,” with music by David Newman and computer-generated animated film produced and directed by Chris Young and designed by Yoshitaka Amano. The work is a co-production of the Philharmonic, Hyperion Studio, Richard Kraft, Lyn Benjamin, TEN Prods. and Hyperion Pic-tures Co., Japan. The performances take place from April 30 to May 3, 1998, at the Dorothy Chandler Pavilion, with Philharmonic music director Esa-Pekka Salonen conducting. In an unusual move for the Philharmonic, the 1997-98 season will also feature works by other film composers: John Williams’ Violin Concerto (Dec. 18, 20, 21) and a to-be-determined piece by Jerry Goldsmith (March 26-28, 1998). In addition to ”Tales From 1001 Nights,” the Phil will give two other world premieres of as-yet-untitled works by Italian composer Franco Donatoni (Oct. 23, 24, 26) and Finland’s Magnus Lindberg (March 12-15, 1998). Other American composers represented are John Adams, Samuel Barber, Leonard Bernstein, Aaron Copland and Lukas Foss. The Ligeti concerts will take place in April and May 1998 with four works spread over three programs, along with additional pieces at New Music Group and Chamber Music Society events. Salonen will lead Ligeti’s “Requiem” April 18, 19, 22, 1998; ”Atmospheres” and ”Lontano” April 24-26, 1998, and guest conductor Pierre Boulez helms Ligeti’s Piano Concerto May 22-24, 1998 (with pianist Pierre-Laurent Aimard). Guest conductors in the 1997-98 season include Roger Norrington — who leads a Brahms symphony cycle Nov. 1, 2, 5 — Oliver Knussen, Paavo Jarvi, Lawrence Foster, Franz Welser-Moest, Jukka-Pekka Saraste, Mark Wiggles-worth, Yakov Kreizberg, Mark Elder and Boulez. Salonen himself will lead 12 weeks of subscription concerts, along with two Pension Fund programs. There will also be visits by a number of touring orchestras, including Vladimir Spivakov and the Moscow Virtuosi (Oct. 31), Mikhail Pletnev and the Russian National Orchestra (April 7, 1998) and Sir Simon Rattle and the City of Birmingham Symphony Orchestra (May 20, 21, 1998).
