This week on Night Lights it’s “Songs of Peace,” in anticipation of the coming holidays. We’ll hear instrumental themes using “Peace” as a title from John Coltrane, Ornette Coleman, and Horace Silver, as well as Louis Armstrong’s 1970 take on John Lennon’s “Give Peace a Chance,” Bill Evans’ improvisation on Leonard Bernstein’s “Some Other Time” that came to be known as “Peace Piece,” Mahalia Jackson’s a capella version of Duke Ellington’s “Come Sunday,” and more.
