Details: A Western is Michael Gordon's extended musing inspired by the legendary 1950s film High Noon, starring Gary Cooper and Grace Kelly. It's about the Wild West, the way of the gun, classic American TV fantasies, and of course the good guys versus the bad guys. Caroline Shaw's How to fold the wind is a mesmerizing choral work that expands on the vocal acrobatics the composer has explored with her Grammy-winning ensemble Roomful of Teeth. The piece is inspired by Japanese origami, using speech, inhaled notes, wordless melodies and innovative vocal effects to fold individual voices together into a complex whole. Released together as a "split album" on CD, the two works mirror each other in a compelling array of contrasts and similarities. Each was recorded by one of Denmark's premier vocal ensembles - A Western by Theatre of Voices, How to fold the wind by Ars Nova Copenhagen - with each performance conducted by Paul Hillier. And although the lyrical forms of each piece couldn't be more strikingly different, somehow they elevate each other into a revelatory listening experience that expands the scope of modern choral music.
