Jamaica Plain’s Reverend Dr. Ray Hammond of Bethel AME Church will take part in the upcoming Cambridge Symphony Orchestra's (CSO) Heroes and Angels concert. Hammond will narrate the words of Dr. Martin Luther King, Jr. in a piece by composer Joseph Schwantner called New Morning for the World (“Daybreak of Freedom”). CSO Music Director Cynthia Woods selected New Morning for the World along with the other works on the program, Nan Schwartz’s trumpet tone poem Angels Among Us and Jean Sibelius’ stirring Symphony No. 5 because they complement each other in various ways and remind us that we are creative beings surrounded by natural beauty. In advance of the March 17 concert, Reverend Dr. Ray Hammond answered a few questions for Jamaica Plain News about his involvement in the program.
