Trinity Wall Street has announced a major, multi-year commissioning project, entitled Mass Reimaginings. In coming seasons, the composers Netsayi, Jonathan Newman, Paola Prestini, Sarah Kirkland Snider, Julian Wachner, and Daniel Felsenfeld, who is curating the project, will write contemporary responses to the traditional mass. The first of these commissions, by Felsenfeld, on a text by Rick Moody, will have its première on Dec. 30, as part of Trinity's annual Twelfth Night Festival. Wachner, Trinity's music director, will conduct. The six works will be heard en masse, as it were, in 2018, as part of a celebration of the centennial of Leonard Bernstein; at that time, the great man's Mass will join the throng.
