The opening night of the 2015 Resonant Bodies Festival highlights each performer’s most distinctive repertoire, including works by composers with whom each has had a close working relationship, performed with longtime collaborators. Tony Arnold traces a lineage from Webern to Kurtág (with whom she has worked closely) to Jason Eckardt (whose music she has premiered and recorded) and beyond, to new works written for her in 2015. Dawn Upshaw’s set features Shawn Jaeger’s The Cold Pane, written for and premiered by her in 2013, accompanied by new-music ensemble Contemporaneous. Upshaw will also be joined by her longtime collaborator, pianist Gilbert Kalish, with whom she has premiered numerous works. Lucy Shelton’s set includes signature works written as well as works by Milton Babbitt and Elliott Carter, and world premieres by Eric Nathan (recipient of the Guggenheim Fellowship and Rome Prize), Susan Botti and Icli Zitella. Shelton will be joined by clarinetist Carlos Cordeiro, and cellist Meaghan Burke.
