Jaap van Zweden won't take over as the Dallas Symphony Orchestra's new music director until the 2008-09 season. But all eyes and ears will be on him as he conducts three programs in the orchestra's 2007-08 Texas Instruments Classical Series.

As music director-designate, the Dutch conductor will lead two of five fall programs cycling through the complete Beethoven symphonies. He'll return in April to conduct the Verdi Requiem. And he'll be thoroughly involved in planning for his first full season.

Now that the music director search is over, the lineup of guest conductors is a little less charged than in the last two seasons. And there will be a lot of guests, some just beginning to make their names.

Up-and-coming conductors will include JoAnn Falletta, Eri Klas, Gilbert Varga, Markus Stenz, Arild Remmereit, Peter Oundjian, Ludovic Morlot, Douglas Boyd and Giancarlo Guerrero. Mature practitioners will include Claus Peter Flor, DSO principal guest conductor since 1999; Hans Graf, music director of the Houston Symphony Orchestra; Günther Herbig; Yan Pascal Tortelier; Jiri Belohlavek; and Pinchas Steinberg.

American music will be a recurrent thread. John Corigliano's 70th birthday will be marked by Dallas premieres of his new Percussion Concerto, a DSO co-commission for percussionist Evelyn Glennie; his Red Violin Suite, with DSO concertmaster Emanuel Borok; and his 30-year-old Clarinet Concerto, with clarinetist Richard Stoltzman.

John Adams' 60th will be observed with two of his most popular works, the Violin Concerto and Short Ride in a Fast Machine. Steven Stucky's Second Concerto for Orchestra will get its DSO premiere. And music director emeritus Andrew Litton will return for an all-Bernstein concert marking the 90th anniversary of the late composer's birth.

Solo debutants will include pianists Ingrid Fliter and Kirill Gerstein and cellist Pieter Wispelwey. Although the young American pianist Jonathan Biss has performed with the DSO in Vail, Colo., he'll make his Dallas debut.

The DSO will continue its Casual Fridays series, six shortened Friday performances starting half an hour earlier.

The Deloitte Pops Series will feature a 40th-anniversary production of the rock musical Hair and the film classic The Wizard of Oz with live-orchestra accompaniment. Guests will include the Smothers Brothers, Bernadette Peters, Amy Grant and Jim Brickman.
