Music in Review - Trinity Choir - NYTimes.com As Julian Wachner, the music director of the Trinity Choir and Trinity Baroque Orchestra, said before a concert at Trinity Church on Saturday evening, "It's no small feat to throw together a B minor Mass in three days." He was referring to Bach's monumental work, which the ensembles prepared at short notice for a fund-raiser dedicated to victims of Hurricane Sandy. Mr. Wachner added that they could have chosen something easier, but that this piece - a Roman Catholic Mass by a Lutheran composer - "speaks to a wide variety of human emotions." Contemporary performances of the Mass often feature large, modern orchestras and huge choirs. At the other end of the spectrum are interpretations using a pared-down chorus with only one or two singers per voice part who also sing the solos, as advocated by scholars like Joshua Rifkin. Mr. Wachner chose a Rifkin-type approach: "a slightly radical interpretation," he called it. A single voice sang each choral part when there was no violin doubling, producing lithe, transparent textures instead of a weighty sound. A few muddy orchestral passages apart, Mr. Wachner led a polished, buoyant and joyous rendition of the Mass, during which donations were collected. The choir produced a full-blooded sound that belied its small size, boosted by spirited playing from the period-instrument orchestra. The vocal soloists - who included Sherezade Panthaki, Jolle Greenleaf, Dashon Burton and Kirsten Sollek - sang beautifully. Trinity usually streams concerts live online, but since its equipment was damaged during the hurricane, the concert will instead be broadcast on Tuesday evening by WQXR (105.9 FM in New York).
