Gay or straight: can you hear the difference?

A recent article in the Dallas Morning News examined how some of America's signature music was written by gay composers, including Copland, Bernstein, and Barber among others. By contrast, 20th century composers writing in a more complex, thorny, and modernist style tended to be straight, including Charles Ives, Elliott Carter and Roger Sessions. We look at the issue with the article's author, music critic Scott Cantrell, and play some examples. Also: There is more to sound recording than just recording sound. Far from being simply a tool for the preservation of music, the technology is a catalyst. This is the clear message of the new book Capturing Sound: How Technology Has Changed Music. We visit today with the book's author Mark Katz.
