On September 22, the ISO will debut Uwe Lohrmann's Symphonisches St‹ck, a work commissioned by the orchestra and dedicated to its 75th anniversary last year. On October 28, the orchestra performs the world premiere of a new work by Brian Current, the winner of the 2003 Barlow Prize for Music Composition at Brigham Young University. The Current piece will also be performed by the American Composer Orchestra in New York next season.

In addition, the orchestra will perform a new percussion concerto by Jennifer Higdon, co-commissioned by the ISO, the Philadelphia Orchestra, and the Dallas Symphony, in March and April 2006. Colin Currie will play the solo part.

Music director Mario Venzago will conduct all three new works.

The orchestra will celebrate the 250th anniversary of Mozart's birth with three programs between January 20 and February 4, 2006.

The repertoire includes Robert Levin's completion of Mozart's Mass in C minor, which recently premiered at Carnegie Hall.
