In Thursday’s (2/26) Orange County Register (California), Timothy Mangan writes, “The Pacific Symphony unveiled plans for its 2009-2010 concert season, the orchestra’s 31st, at Renée and Henry Segerstrom Concert Hall on Wednesday morning. Conductor Carl St.Clair will be celebrating his 20th season as music director, and many of the offerings are designed to mark the occasion. Several noted guest soloists have been invited back to do just that. The orchestra also announced the receipt of a $500,000 multiyear grant from the Andrew W. Mellon Foundation that will be used to launch a new series, ‘Music Unwound,’ aimed at redesigning the traditional concert format with multimedia. … A two-year commissioning program will bring new works by Richard Danielpour, Michael Daugherty, William Bolcom and Zhou Long. Danielpour’s Piano Concerto and a choral work by Daugherty, based on the poetry of Carl Sandburg, will be premiered in the first year. The annual American Composers Festival, which will mark its 10th year, will look at ‘The Greatest Generation,’ focusing on music created during and in response to the Great Depression and World War II.”
