Soloists include soprano Deborah Voigt and Heidi Grant Murphy, tenor Johan Botha, and bass John Relyea. Mezzo-soprano Lorraine Hunt Lieberson was also scheduled to appear, but withdrew earlier this week, apparently because of a back injury. She has been replaced by Yvonne Naef.

The BSO's performances at its summer home in the Berkshires run through August 28. Levine will lead the orchestra in a total of six programs, including performances of new works by John Harbison and Charles Wuorinen that received their world premieres as part of the BSO's 2004-05 season.

In addition, Levine will lead the Tanglewood Music Center Orchestra, an ensemble of the young musicians in training at the center, in the annual Leonard Bernstein Memorial Concert. The concert on July 16 will feature excerpts from Wagner's Die Walk‹re and G‹tterd‹mmerung and will star Voigt and other Wagner specialists.

Other conductors leading the BSO during the summer season include Marin Alsop, James Colon, Charles Dutoit, Hans Grad, and Kurt Masur; among the guest soloists will be Emanuel Ax, Joshua Bell, James Galway, Lynn Harrell, and Yo-Yo Ma.
