The recent Tiny Desk concert featured The Crossing, an acclaimed vocal ensemble hailed as "America's most astonishing choir." Led by their forward-thinking director Donald Nally, The Crossing has earned accolades and two Grammy awards for their precise singing of new music. During the performance, the choir showcased "Titration," a brand new work by composer Shara Nova that had its world premiere just days before at a concert in Montana. The Crossing, based in Philadelphia, is known for commissioning and debuting numerous new works by renowned composers like Caroline Shaw, David Lang, John Luther Adams, and Gavin Bryars. Their dedication to pushing boundaries in choral music and collaborating with various artists and ensembles marks them as a pioneering force in the contemporary choral landscape.
