Symphony, Musicians of London, Sinfonia of St. Martin-in-the-Fields and the Central Philharmonic Orchestra of Beijing. In the United States, he has conducted such groups as the San Francisco Symphony, Pasadena Symphony, Pacific Symphony, Inland Empire Symphony, and El Paso Symphony. His professional organization, the William Hall Chorale, was under contract to Columbia Artists Management for over thirty years and sang throughout the U.S. and abroad. Chorale tours included the former Soviet Union, China, Australia and New Zealand, and frequent tours to Europe. Following the Chorale’s concert in Vilnius, Lithuania, William Hall was knighted by the officials of the capital city and presented with the “Order of Vilnius.” The William Hall Chorale performed on a regular basis in Southern California, appearing regularly at the Los Angeles Music Center, Hollywood Bowl and the Orange County Performing Arts Center. The Master Chorale of Orange County and the William Hall Chorale were both conducted by Maestro Hall, and later merged to form what critics called a “Super-Chorale.” In addition, the Chorale collaborated with such internationally renowned companies as the Joffrey Ballet, Bella Lewitzky Dance Company, San Francisco Ballet, Zubin Mehta and the Los Angeles Philharmonic Orchestra, Michael Tilson Thomas and the New World Symphony, Keith Lockhart and the Boston Pops Orchestra, and Sir Simon Rattle and the City of Birmingham Symphony Orchestra.
