William B. Miller of midtown’s Trinity Episcopal Church sees no conflict in synthesizing jazz and spirituality. Since 2002, Miller has spearheaded the Trinity Jazz Festival to display not only the beauty of his house of worship but also its commitment to artistry. “Though jazz in the sacred context may be rare, it is a pairing that makes much sense — theologically, historically and liturgically,” he says on the Festival’s website. “Sharing some of the same roots as indigenous gospel music, this art form is rightly at home in the sacred context.” This year’s lineup of musicians performing and/or teaching master classes includes pianist Pamela York and saxophonist Everette Harp on Friday, with vocal duo Mood Indigo and guitarist Eric Essix on Saturday. But for many, the festival’s highlight will be the jazz mass on Sunday.
