As the orchestral world strives for greater diversity among musicians, a variety of programs to support musicians of color, who face multiple challenges on their path to an orchestral seat, have been explored. Recently, three organizations that have been tackling some of these issues - The Sphinx Organization, The League of American Orchestras and the New World Symphony - have brought their expertise and experience together, joining in a partnership to launch the National Alliance for Audition Support. This Saturday (4/21 at 7 pm) A Tempo host Rachel Katz will look into this initiative in a conversation with Sphinx Organization President and Artistic Director Afa Dworkin, League of American Orchestras President and CEO Jesse Rosen and New World Symphony President Howard Herring.
