Swann, the president of the American Guild of Organists, is one of the highest-profile organists in the United States, having played at New York's Riverside Church and at the Crystal Cathedral in Orange County, California, the site of Robert Schuller's "Hour of Power" television ministry.

The new organ is featured in a series of recitals over the course of the season, as well as several Los Angeles Philharmonic performances, starting with orchestra's opening-night gala tomorrow night and its performances on October 2 and 3. On October 7, organist Wayne Marshall will be the soloist in the Philharmonic's world premiere performance of James MacMillian's A Scotch Bestiary, for orchestra and organ.

The organ, which took a year to install, tune, and voice, is the latest addition to Disney Hall, a swooping, steel-sheathed hall designed by Frank Gehry. The hall opened in the fall of 2003 and has rapidly become a Los Angeles landmark.
