Soprano Tony Arnold is a major American advocate for contemporary vocal music, participating in more than 100 world premieres. Arnold's definitive move toward vocal music came at Northwestern, where she was recruited by members of the contemporary chamber group Eighth Blackbird for a performance of Lukas Foss' Thirteen Ways of Looking at a Blackbird. In 2005, Arnold made her recording debut on an album featuring George Crumb's four books of madrigals. Arnold is the soprano with the International Contemporary Ensemble. She has appeared with leading U.S. contemporary chamber ensembles, including the JACK Quartet and Ensemble Modern. Arnold was featured in 2023 on the album Eric Nathan: Some Favored Nook. By that time, her recording catalog comprised some 30 items.
