With Appomattox, the composer has chosen a historical topic that lends itself to an arched yet linear narrative leading to a well-defined climax. And judging from his newer works, his compositional style has acquired a surprisingly lush lyricism. One might suspect Appomattox of being Glass's first opera in grand 19th-century style, although the composer reassured those who fear he might be softening with age, "It is going to be a very confrontational piece. Some of the elements will be quite difficult for some people."Glass also commented on the significance of the war today:
One such element is Appomattox's score, which integrates Old Testament hymns sung by black Southerners to welcome Abraham Lincoln during his visit to Richmond, Va.; military songs by the Arkansas First Brigade; and civil rights ballads.
"I wanted to include in the musical language the feeling and the musical culture of that time and of the present time," Glass explained. "While this was written for voices skilled in operatic singing, there are other kinds of music in this opera as well. This was for me one of the most interesting things, to try to bring together different music that would normally not be heard at the same time."
"The issues that were raised at the time are very much at the heart of social change in our country today: states' rights, racism, you name it," Glass said recently from his home in Nova Scotia. "On the good side, we are still engaged in resolving these issues. That is one of the great things about our country, that we haven't shied away from the issues. We embraced the difficulties as we tried to find solutions. We had some measures of success and some not. But [these issues] never stopped being relevant, because they were never resolved."
